"tmobile diagnostics keeps stopping" galaxy s20 pop-up

Same here on an LG V60.  Went through three chat sessions trouble shooting and one with tech support.  They 'sent' something to my phone last night but the issue popped up again.  They've ask me to do a hard reset to see if that clears.  Has anyone else tried this yet to see if it clears out.  Even with LG backup or Google backup it's a pain having to make sure everything (passwords on secured sites like banking apps) went back in.
