I cannot open messenger on my iPhone 15 Pro

Have you tried to delete the messenger app and then reinstall it?

Same thing was happening to me… Delete and reinstall the app. Then it will work.

What version of iOS are you using and have you updated the Messenger app?

I just bought an iPhone 15 Pro Max… Messenger won’t open… I’ve tried shutting the phone off, gone into the App Store, and when I press to open it, it just jumps back to my Home Screen
