Re: "Since the update on 20250406 the Numbers folder is nowhere to be found. The program still appeared to have three of the six documents available but they were not the latest versions. Three complete documents which took a lot of time and work have just vanished.
If I search the files root folder a folder called numbers is found but it is not accessible, i.e. clicking on it just brings up nothing. Anyone got any bright ideas?"
See if one or more of the suggestions below can help find / uncover / restore the missing files:
✽ Check the available memory / storage on your iPhone: Eg: An iPhone needs around 8 Gb free in order to operate smoothly. If files were deleted in order to complete the update, and continue using your iPhone, files that can easily be replaced are sometimes deleted.
See: How to check the storage on your iPhone and iPad - Apple Support
✽ Check the "Recently Deleted" folder ... eg: it usually contains deleted files for 30 days
See: Delete files or recover deleted files in the Files app on your iPhone or iPad - Apple Support
✽ Try searching for the missing shopping list-files themselves, (ie: not just the Numbers folder.)
Find files on your iPhone or iPad in the Files app - Apple Support
Eg: says:
Types of files stored in the Files app
- Under Locations, in On My [Device], you can find files stored locally on the device that you're using.
- Under Locations, in iCloud Drive, you can find files and folders that sync to iCloud Drive, including Pages, Numbers, Keynote documents, and more.
If you use iCloud: If you can’t find a spreadsheet in Numbers for iCloud - Apple Support
✽ Wondering if you backed up your Numbers files with your iPhone data before updating.
If so, you may want to restore that back-up. (Back-up again first so you retain any new or changed files. )
