I used to ignore my screen time limits that I set for myself if the task was important, but when I download IOS 18 Beta, it doesn't allow me to ignore any apps limits despite trying to restart and troubleshoot
Ignore Screen Time NOT working on IOS 18
Yes, if you search these forums you'll see lots of reports of this bug.
But the Developer Forums aren't really the right place to raise bugs in a new version of an OS. Apple's engineers aren't reading through these pages to see if anyone's found a bug.
These forums are for third-party developers writing apps for Apple's platforms to discuss issues with their code.
You need to raise each issue you find separately at https://www.apple.com/feedback/ You can post the FB numbers here if you want, so that others can link to them.
I went to the feedback app and sent reports, you should too. I have the same issue aswell.
