Been paying annual subscriptions for years and watching Teamviewer getting more and more complicated to use, and adding more and more unneeded features. Past months after they introduced the new interface, it finally broke me. Spent 2 months on and off trying and hoping it could be just my end (settings, connectivity, going back to older versions, etc) but no, it is not me. Often enough I just could not get connections. When I could, it would just freeze up and exit out. Something is wrong with their servers / ends. They told me it is just me and no one else has the same problem. I DO NOT BELIEVE IT.
Trying out alternatives and be done with Teamviewer.
