Disable autosave IOS 16.3

Apple invite submission of feature requests via its Product Feedback portal. For iPad and iPadOS:

Feedback - iPad - Apple

If you haven’t already submitted the request via this channel, this would be the most appropriate channel through which to do so.

Having tested this myself, with both the Numbers and Pages Apps (they both work the same way), I cannot replicate your problem. The instructions within the Guide appear to be correct:

As such, either there are no related document versions - or something isn’t quite right with your iPad. In case of the latter, perform a forced-restart of your iPad - as this will often clear an isolated software issue:

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

Force restart iPad (models with the Home button)

Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.

The Pages User Guide for iPad is a rich source of information - that includes details of how to restore an earlier version of a saved Pages document.

Here is a direct link to the appropriate section of the Guide:

Restore an earlier document version in Pages on iPad - Apple Support

Having tested this further, document history does appear to be limited to documents stored in iCloud. This limitation appears consistent for both Numbers and Pages.

Whether or not this is an undocumented functional limitation - or is perhaps bug - we have no idea. As such, you would be best advised to seek assistance directly from Apple Support.

You can contact the Support Team using the Support link at top-right or bottom-left of this page. Alternatively and perhaps easier, you can initiate and manage your support cases using the excellent Apple Support App. If not already installed on your iPad, the App can be downloaded from the App Store:

Hopefully the Support Team will be able to provide appropriate guidance - and/or escalate the issue to the App Developers.

When you learn more, please return to this thread with any information that you may learn - as this will doubtless help others that encounter this issue.
