When I try to share any file I get an error "We've interrupted your sharing activity. For details or to contact support read our help center article".
I read the article and I can't find any files that could violate the terms. I don't understand what is the reason for the blocking.
I created a simple test .txt file with the word test in it and I can't share it.
This happens on both the desktop app and the web app.
I've been able to share/transfer files in the past without any problems (last time was probably a couple of months ago).
