We are developing an app that monitoring iBeacon in the background, when the iPhone entering in the beaconRegion, iOS could wakeup the app. Before iOS15, it works well. Unfortunately, when update to iOS15, it sometimes cannot wakeup the app. This seriously damages the user experience. And other developer also meet the same problem, like this https://stackoverflow.com/questions/69440565/regioncircular-and-beacon-detection-in-background-sometimes-fails-in-ios-15
Could you fix it? Thanks
