I did the 11.4 update on my 8 and X and the phones are a wreck. I decided to start over from scratch last night and things are not better. I erased everything and only brought back my texts. Good grief.... like the camera only loads about once every 10xs I try. It is studdery too on my 8. I couldn’t pair my watch and that finally worked. Every app I use has to be restarted and sometimes the internet doesn’t work. Phones are in different networks. The 8 was just replaced. Neither is damaged. Anyone else having insane issues?? So many more I don’t have time to type.
