  1. My iPhone XsMax some of app not working like tik tok, botim other apps also but YouTube is working fb in these are working but when I connect other wifi then al are working

    • I’ve had some success with turning off the location services toggle. (Privacy and security— location services toggle) I had tried all the suggestions that I could find and zilch. This was a last stab before I brought the IOS back to a previous version something I really didn’t want to attempt. This has improved the connectivity of my iPad pretty well. It’s not perfect and I miss location services and now have to turn it back on ever so often for weather and map apps. Still waiting for the fix but it has saved me from throwing the iPad across the room.
