Thank you, but I don't even have that section within settings > messaging. All I have there is (1) Show Link Preview (2) Compress Files (3) Voice Clips (4) Archived Teams. This is from my mobile - iPhone 13 mini. 

I cannot figure out how to disable popups at all anymore.  After the upgrade, there seems to be no way to disable them. I do NOT want messages to fly onto my screen while I'm doing something else. I wish this was easier to disable. Please help!
