Our app has suddenly started exhibiting a strange delay when resuming from the background; it gradually takes longer and longer to reactivate the UI. Eventually, the app takes several seconds to resume, and crashes for failure to resume in time.
I looked at the crash log, and found four threads with identical call stacks. Anyone know what might be the problem here? We use CoreLocation, but I don't recall changing anything about our use of it in many weeks (this problem seems to be new). Thanks for any insight.
