Yellow triangle pop up Blizzard Error

I tried logging into Battlenet and a yellow triangle Blizzard Error window popped up asking me to describe what I was doing when the error occurred. Is anyone else having this issue?

This happened to me a couple of days ago, when I was doing nothing: not trying to log in, not trying to authenticate, not doing anything in the Battle.net app. It has happened very occasionally throughout Shadowlands.

I responded as above to the “What were you doing?” questions and sent my report off to Blizz and .

It has happened to me every day I try to log in and I did submit the report but still couldn’t get in.
