PROBLEM SOLVED!!! Hit the power button, then hold down your power button and restart in Safe Mode. Once in Safe Mode, restart phone in regular mode. THIS solved the problem with the messages popping up every 10 seconds. Note, I did do a network connection reset like the other posts suggested, but it didn't work. Maybe the combo of both cleared it out. But ever since I did this, no message pop-up. 🤗🤗🤗 Good luck!
I have a note 9 and had the same issue. I tried resetting connections but that didn't work. I tried this and it's been about 10 minutes with no popup message so here's hoping.
Well, my issue has come back. It's driving me CRAZY! Now, I'm going thru every single app on my phone, because ATT says it's a problem with my apps. Well, this WASN'T a problem until they did the Update. UGH.
