In case anyone is wondering or still chasing this. I spent since the update until now talking with Apple and multiple phone carriers that I had switched between to fix the problem.
I’m not sure if anyone noticed or anyone else has this but I also can not use my hotspot and do not have this option anymore.
The end result is that it is an APN issue and because of the way Apple works, unlike android, you can’t just jump into your settings and fix this.
I ended up speaking to some higher up in Apple support, who was incredible by the way, and they are aware of the issue and as of now, the only fix is to backup to the cloud and factory reset your phone.
Because I can’t do this she assured me that if I waited for the next update there would be something in that, that would fix this issue.
