I've also had issues with the iOS 13 on an iPhone X. Mail notifications appear but the messages don't download for 30+ seconds, and sometimes notifications don't disappear.
Just got an 11 Pro and some notifications don’t vibrate, other notifications no longer show up even though they have permissions to and are set to. Sometimes iMessages won’t vibrate either.
It’s a mess and I can’t trust my phone to notify me. Now I have to constantly be checking it
Add in that alarms randomly don't fire, or fire at the wrong volume. I'm using my old phone as my clock and timer. I wonder if it's related to the bonkers notification settings.
Either way, disaster of a phone, and disaster of an OS.
