Collaborate on a shared document in Pages for iCloud
Whether you’re the owner of a shared document or have been invited to collaborate, you can see the edits made by others in real time, hide or show editing activity, and more.
The number of people editing or viewing the document (not including you) appears beside the Collaborate button 
in the toolbar, and their names (or email addresses or phone numbers) appear in the participant list.
Accept an invitation to collaborate
When you receive a link to a shared document, what happens when you click the link depends on the access and permission set by the owner, and on the version of Pages and macOS installed on your computer.
Before you begin, make sure you meet the minimum system requirements for collaborating.
Click (or tap, if you’re viewing the invitation on iPhone or Pad) the link in the email, message, or post you received.
If asked, sign in with your Apple ID or follow any instructions that appear.
The document opens based on the following:
On a Mac: The document opens in Pages for iCloud or in Pages for Mac.
On iCloud.com on a Mac or Windows computer: If you’re signed in to iCloud.com, the document opens in Pages for iCloud, and it’s added to your document manager and to iCloud Drive.
On an iPhone with iOS 13.1 or later and Pages 10.2 or later: The document opens in Pages on your device and is added to your document manager.
On an iPad with iPadOS 13.1 or later and Pages 10.2 or later: The document opens in Pages on your device and is added to your document manager.
On an Android device, or a device without iOS 13.1, iPadOS 13.1, or later; and Pages 10.2 or later: The document opens in a supported browser where you can view but not edit it.
If you can’t open a document that’s been shared with you, it’s possible the email address or phone number used to invite you isn’t associated with your Apple ID. Sign in with your Apple ID, then follow the instructions to verify your email address and associate it with your Apple ID. Then click the shared document link again.
Note: If you don’t want to associate another email address with your Apple ID, you could instead ask the owner of the shared document to invite you again using an email address or phone number that’s already associated with your Apple ID.
Collaborate on a shared document
Open the shared document.
If you don’t see the document you’re looking for in the document manager, click the link in the email, message, or post you received, and if asked, sign in with your Apple ID.
If you can’t open the document, see Accept an invitation to collaborate.
Edit the document.
Edits you and others make to the document appear in real time. Colored cursors and colored selections of text and objects indicate where others are currently editing.
Note: If a shared document uses the formatting conventions of a language other than your primary language, a message near the bottom of the document indicates which formatting is being used.
Do any of the following:
See who’s working in the document: Click the Collaborate button
in the toolbar to see the participant list, which shows who has joined the document and who is currently editing or viewing it. If you’re the owner and the access is set to “Only people you invite,” you see the email address or phone number (instead of the name) for people you’ve invited but who haven’t yet opened the document.
Follow someone’s edits: Click the colored dot to the right of the name to see where that person is working. If you don’t see a colored dot, the person doesn’t have the document open.
Hide or show activity (colored cursors or selections): Click the View button
in the toolbar, then choose Hide Collaboration Activity or Show Collaboration Activity.
Opt out of a shared document
If you no longer want to have access to a document that was shared with you, you can remove yourself from the participant list.
Do one of the following:
With the document open: Click the Collaborate button
in the toolbar.In the document manager: Click Shared (on the left), then select the document. Click the More button
, then choose Collaboration Details.
Move the pointer over your name, click the three dots that appear, then choose Remove Me.
Removing your access removes your name from the participant list and removes the document from your iCloud Drive. If you later want to access the document again, click the original link to open it.
Locate documents others have shared with you
Try any of the following:
Find the shared document link that was sent to you (in the original email or text, for example), then click it.
If you’ve opened the document before, click Shared on the left side of the document manager, then look for the document. If there are more shared documents than fit in the current view, click See All in the upper right.
If you delete a shared document from the document manager and later want to see it again, just click the link you originally received. As long as the document is still being shared by its owner, the document reappears in the document manager.
