If you try to read a file from Files app it fails after 1-2 minutes with FileError code 1 (NOT_FOUND_ERR). How to reproduce: 1) Open https://stat-info.cz/safari-ios13-upload-from-files.html 2) Select Blob size (50 KiB should be enough for 2.5+ MiB files) 3) Click "Choose Files" button -> Browse -> Pick some file from your device 4) Now the script reads the file at rate 1 Blob/s and you can see how it fails after 1-2 minutes. This problem is not happening if the file is picked up from Photo Library.

Looks like this is not happening if you use drag&drop on iPad. So maybe this problem is related to input[type=file] only.

Glad to say that for me (running iOS 15.5) this is no longer an issue. I think this issue can be closed off.
