Nothing I delete from within Textastic ever shows up in the Recently Deleted folder.
I can create a test folder containing a test text file from within Textastic. I can go to the Files app and see the newly created folder is visible from there in iCloudDrive. Then go back to Textastic and delete the folder. Go to the Files app and look for the folder. It will no longer be visible in the Files app under the iCloudDrive folder, which is correct. When I next go to the Recently Deleted folder, the folder I deleted is not there.
I can delete a file and it never shows up in Recently Deleted even though it shows up in the Textastic folder.
