This was just an error while internal testing, not to worry about it
I found the same thing. What's going on Samsung?
I received the notification as well, when I clicked on it no action happened and it disappeared. I read it was some kind of internal glitch at Samsung so no big worries there I guess.
Yup just woke up clicked it then it dissapeared
I received the same thing this morning. I clicked on it and it disappeared. But ppl are saying it was a glitch
Had the same message on my S10, thought someone had hacked my phone
I got this notification just now as well on my S9 plus.
