Android 2.0 App used all of my mobile data

Nextcloud 2.0 app just used all of my mobile data today.

I think was happened is I have been having issues uploading Large files. I have a few videos large videos I have recorded that have been attempting to auto upload but this issue has been going on for months. I have it setup the only upload on WiFI so it hasn’t really been a problem.
Apparently with the Android 2.0 this was ignored?
