I had the rather unpleasant experience of wanting to use TeamViewer but being unable to log in. I was not home & I was trying to connect to my home computer. I discovered after I got home that the problem was not that I was logging in incorrectly. The problem was that my TeamViewer ID number had changed & I had not been notified of this event. I suppose it's not really a problem that the ID changed. It's a problem that you didn't tell me you were doing that. I am requesting that you E-mail me when you do something like that. Don't just put a notification in the app. I open TV only occasionally, being a non-commercial user & having only occasional reason to use it. Notify me by E-mail. You have my E-mail address. It's part of my login process, not only in the app but here on the web site. I expect you to take this suggestion to heart & implement it forthwith.
