I'm using the Team Viewer Quick Support App for Samsung (I have it loaded on over 30 tablets). When I went to load it on 2 new tablets it didn't provide an ID Code and at the bottom of the screen I have a yellow message saying: "Activating TeamViewer...".
I tried uninstalling and reinstalling the app and I tried installing it on 3 different tablets and am getting the same result.
I don't kow how to fix this problem but I need to have remote access to these tablets
I strongly suspect that this issue is caused by firewall rules on your WiFi. If you connect via 3G/4G on your Samsung, or via Personal Hotspot on an iPhone (or equi. on an Android phone), it might work.
