iOS 18 issues on iPhone 13 Pro Max

All notifications are not working. Miserable!

I can’t get any notifications and now my apps won’t work unless I pay for them with my debit card I don’t like that

I have a 13 Pro Max as well, and iOS 18 has been a genuinely unbearable experience. My phone battery has been absolutely shot, my phone is laggy, and don't even get me started on the absolutely infuriating photos app experience. Typing is slow, my browser is slow, and in the time it took me to make this account and type this message my phone battery has gone down 10% on low battery mode. This is incredibly unsustainable as I am a student and can't access a phone charger the entire day.

Same here! My iPhone 13 Pro Max and my iPad both are lagging so much it’s unbearable! I really hope Apple fixes this ASAP.. any suggestions on how to fix it?
