I don’t see any problems with the script itself.
There is perhaps one thing, the “TAGS ON” mode, which is useless in this case.
Also try removing the “Sound notification” url in “Sound configuration”, it triggers (even if set on the global source) an additional notification in parallel. Just empty the field, the sound upload won’t be removed.
Try all this. If it’s still there, tell me the attempts that didn’t succeed (with the time and the person who initiated the command).
