For me I had screen time on for 3 apps and I had it on for about a minute just reminding me to not watch it a lot in the morning and when I downloaded the IOS 18 beta, the Apps work perfectly fine and then after 1 minute they almost crash! Theres no sound, I can’t send any videos and on one of the apps nothings working. I’ve tried everything like turning screen time off completely off all my devices and disabling everything but nothing seems to work. I’ve provided this in the new feedback assistance, but I would like this bug to be fixed as soon as possible so I can start accessing those apps again!
