Hi. Do you have a source for this? By the way, enabling the showsBackgroundLocationIndicator flag has worked for me too.

We are still seeing this issue on iOS 15.1 on the app that we work on as you say this had been working fine on iOS 14 and below. I reported this bug using the feedback assistant and I encourage you to do the same. Hopefully, this is sorted out soon.

I am seeing this same behavior on Xcode 13 beta 5. This takes a huge amount of time to build the project regardless of this was already built or not.
