I'm experiencing the same issue. This is the first time I've ever seen this happen. One of my apps has been stuck in "Waiting for Review" for over 3 weeks with no Resolution Center messages or required action, while another app from the same account was reviewed in just one day. I've honestly given up trying to understand what's causing it.

The Asset Packs link is now available in the Distribution tab.

I have the same issue, I dont know how to fix it. and yes the only way to make the widget render again is to reboot the phone!

Hello Does anyone have an answer to this question? I couldn't figure out how to hide the dynamic island and show only Live Activity.
