Since the latest update to the pages/numbers/keynote "can't open file"

I used your comment but was too lazy to walk into the computer room. So I successfully used the following.

1. I deleted the numbers application from my iPad and rebooted it using sari reboot device command.
2. i reinstalled the numbers application and found the templates available but not the files which were greyed out.
3. I again rebooted the iPad with the sari command.
4. All of the files appeared in bold and I opened the three critical ones successfully.
5. the update I made from my iPhone that caused all the problem had the update when opened.

I deleted Keynote on the iPad and re-installed it and it worked.

I tried to delete them and then reinstall them. no dice. I then deleted the apps and restarted my phone and it worked for Pages, Numbers, and Keynote.

I'm running an iPhone 7 Plus with 13.2.3.

Have you updated to iOS/iPadOS 13.2.3?

I have the same problem. I updated a numbers file on my iPhone 6+. I am locked out of all iWork files on iCloud from my iPad as a result. Your systems will not save to local with the old files either. My iPad is 13.2.3.

This is a real pain probably facilitated by the iCloud approach to godliness. The iCloud is supposed to be a tool, storage device, not a block to using my iPad.

ho do i get direction on reverting to old version as the error message asserts? Is that the OS, application, or file version. I auto update my iPad (never again)

Backups? On cloud or Mac?
