There may be an error in data transmission

[wershner]

I tried to find that I transferred a 6M file, but there may be a phenomenon that the data saved after the completion of the scan progress bar is 0K or 16/32K, and no error was reported during the scanning process, but it is still considered to be an effective transmission and cannot be used stably.

Were you able to save the file from the initial decode? Or did something else happen?

I'm not 100% sure I understand the scenario you're describing, but I can say that successive attempts (after initial decode) to on the same "file" will be treated as no-ops. That is, since the file is marked as done, progress is automatically ignored (the progress bar still updates though...). Closing+restarting the app will reset things into a clean state.
