The last-channel and duplicate-logo glitch appears to have stopped...no thanks to Cox. I cleared my History in the Last Watched section and everything appears to be back to normal.
The Caller ID glitch, however, still exists. My Mom called 3× for Thanksgiving and my call-blocker blocked her. If there is no Caller ID data with an incoming call, my call-blocker will automatically block the call. It's a good call-blocker and has worked flawlessly since 2011. I've changed nothing with its configuration or anything on my telephones to have created this problem. Cox had changed something with its Caller ID data.
I did receive Caller ID info with the following call: (888) 769-0137 [800 Service]. That number has been a well-documented scam since 2016 and its been the only Caller ID info I've received in a week.
Why is Cox supporting Caller ID info for nuisance calls but denying it for family? This is getting ridiculous.
