How could I get rid of these annoying popup notifications like "File transfer started" or "File transfer completed". They don't disappear automatically, they can be closed by manually clicking on them. It is really annoying and disappointing issue, since they are several thread (for example: thread 1 or thread 2 in which they say the issue has been solved in a newer version of teamviewer. I use 15.4.445, and the problem still exists. What should I do?
