I deleted 5.3.1 thanks.

Can you confirm that I should be seeing the Textastic folder and files in iCloudDrive?

I don't know how this happened but I have two instances of Textastic installed: 5.3.1 and 8.0.1

I'm concerned about doing a complete delete and restore from the backup on iCloud when I can see the files I want are not there, not in recently deleted, and the last backup was yesterday. I'm not sure what I might lose doing this from other apps or places on the phone, like non-iTunes music.

The folders have been visible within Textastic for months, perhaps a year, definitely visible in the Windows File Explorer under iCloud Drive, which I have installed on my Windows 10 laptop and I am fairly certain I've seen them in the Files app. Everything was fine until the previous time when after deleting a folder from within Textastic, the first folder vanished, from Windows, from Textastic and from the files App. The second one I noticed was gone today and I don't recall deleting anything., except I did create and delete a test directory. I hardly ever delete anything from my Textastic files.

I called Apple support. The tech said several things. He claimed the app files would not show up in iCloud, backup or restore files, he seemed unsure (he thought that was normal). I said the Textastic app folder shows up in the iOS Files app. He then went on to saying I should restore my iPhone (from the cloud) to get the files in sync. And he suggested the files may never have uploaded to iCloud, but that seens unlikely. I can see all the others. I don't see them in the recently deleted.

The first thing I did was look on icloud.com and there's nothing in Recover Files.

The folder was within the Textastic/iCloud/Notes folder and not in Local Files.

I thought because I had iCloudDrive that I would have time to recover any deleted files.
