Since updating my iOS devices to version 11.0.2, I'm not able to login to my Windows machine anymore.
Here's what I've monitored so far:
I don't know what's wrong, but it clearly seems to be a bug regarding TV under iOS11.
I'm currently in touch with the TeamViewer support and they're analyzing the problem.
What I was able to discover so far, is that (at least in my case) it's not working because my password contains double quotes.
