@sconty14 I had the RC installed, it was a different build. So far nothing changed. The 26.6 is only security fixes so far and there are no optimizations anyway besides the spotlight index. Its fine. Just hard reset your phone and try by using WiFi
@sconty14 I installed it just fine on my 17PM. Try to hard reset your device ( vol up, vol down, long press power button). It’s a security fix anyway, you shouldn’t face any problems
