iPhone 15 plus apps lagging/not opening
Recently got an iPhone 15 plus, a lot of my apps take a while to load/open and often have to force close multiple times before loading. (app examples are Amazon, target, instagram, facebook,& some money apps.)
I've tried with WiFi, without WiFi, clearing my background apps, deleting unused apps/items to make space, updating software & apps, Restarting the phone; basically anything I could open source find on the internet. Nothing seems to be working and it's so disappointing to spend $1000 on a phone and it run worse than any iPhone I've had in the past.
Any tips or advice?
