I have been trying to solve the problem for 16 hours. Five minutes after I posted here, I found the problem. I still don't know exactly what is happening, but after removing the PWA, the application started working again. I will continue investigating, but I am leaving this here in case someone encounters the same problem.

we are having the same issue right now. What we realized is that rendermode=interactiveserver page is not working while mobile safari tab is in private mode. SSR pages are working for both cases.
