iPhone 17 pro max: Multiple Apps not working

Just got the new 17 pro max. Moved everything from my 16 pro max to the new phone and have nothing but issues since. YouTube won’t play videos. Just brings up a black box with no sound or video playing. Same with YouTube tv. Apps that require sign in like Disney plus constantly tell me it couldn’t connect or had issues of some kind before I’ve even attempted to input a password. TikTok only plays 1/2 a video before it needs to load. Games like destiny rising get to the homepage but has no server associated with it, and the drop down list for the server shows nothing. Browsing both safari and chrome are incredibly slow. ESPN is also slow.

its not my WiFi or the 5G. Everything I’ve mentioned above works perfectly still on my 16 pro max. I’ve erased everything from the phone multiple times and tried using backups from the new phone and the old phone. Is anyone else experiencing anything similar/have a fix? This is INCREDIBLY frustrating.

Hey, I have iPhone 17 pro max and iOS 26.0.1. YouTube and other apps seemed to have network issues (kept loading/not working properly).

If your iPhone 17 doesn’t work properly & you already did the following:

• delete & reinstall apps that are not working

• restart iPhone

• reset network settings, restart iPhone

• check WiFi and internet connection

• reset iPhone

↑

If you did all that and your apps still have network issues, it could be VPN.

First check if your VPN is off.

Mines was off.

However, if you use apps that ask for VPN (like Survey apps) that’s it. It doesn’t show unless you go into Settings > General > VPN & Device Management.

If you have an app on there that asks for VPN turn that off.

As soon as I did that, it fixed.

Even if you reset network settings, because this is an app setting it doesn’t get reflected and you will continue to have the issue.

I just did that this morning and now my apps work perfectly fine so try give it a try if you’re having issues.
