I'm looking for a solution that does not include replacing a perfectly good smartphone. It looks like a recent update to the Cox Panoramic WiFi Application is no longer compatible with many smartphones out there, including mine of course. This post as of January 24, 2021, so I'd say the stunt happened within a few days before that date. I enjoyed the convenience of making adjustments to my home network remotely. Now that has been summarily taken away. Sorry if I don't appreciate that.
What was the answer/fix...a reinstall?
UPDATE: I Rejected my "answer" 'cause I ain't worthy of a fix.
I tried the chat feature. After explaining the problem and what I did to narrow things down to compatibility with the updated version, the rep indicated she'd look for a solution for me, and then she bailed after a few minutes and no dice for me.
I can't reinstall, because Play Store no longer has a version compatible with my device. The answer seems to be I'm screwed.
