At&t number sync not working
My samsung tablet is sync (paired) to my samsung phone. If my phone is in another room and I receive a call on my phone, I can answer the call on my tablet. It has been great until the tablet had an update. Now the at&t number sync feature is no longer working, when it asks me to login the message says "server had an internal error or timed out, try again" at&t have NOT provided any help with the issue. Any help?
