I had to come back and find this solution! I remembered participating in this thread and not having this problem, but it just started to happen to me.
My guess is a stupid Samsung or Android update jacked with my settings because I also got a data warning and discovered my wifi had been turned off. I didn’t do that, like most people I want wifi to autoconnect all the time so I would never turn that off. Had to be an update.
Clearly the engineers and developers used for phones and apps are not geniuses or their updates wouldn’t screw up people’s phones and apps.
