I have been using the teamviewer app on my android to connect to my office windows 7 pc for a couple years never had a problem. Today I cannot launch teamviewer on my android unless I am connected to WIFI. I get an meesage that says " a connection could not be established please check your internet connection and try again". Every other app on my phone works perfectly without wifi except teamviewer. I had just updated to 13 so I thought maybe that was the problem so I uninstalled it and restored 12 from a backup I had from 2 months ago. No luck same exact problem. I need Teamviewer to work on my mobile data not wifi does anyone know how to correct this problem it's driving me CRAZY!!!!
