I have an iphone 15 pro max and an ipad. My phone's software is up to date. I'm able to download new apps to my ipad, and they open and work fine. I'm having trouble getting existing apps on my iphone to update even though I've got my phone set to automatically update the apps. I mostly can't download new apps. On the rare occasion that they do complete, they get stuck trying to open... the splash screen freezes, or nothing happens and the app times out. No error messages. My phone has 80 GB of space left. I've even reset all of my settings and logged in and out of my Apple account.
Sometimes, one of my bank apps won't open. I restart my phone and that doesn't fix it. I remove it and try to reinstall the app. That can take several tries and days to just to get the app installed. Then after days of that app getting stuck on the splash screen, suddenly it will work again.
I need some other things to try. Thanks.
