Its a personalized running app that gives tailored advice and schedules. I had a few rejections before because I misunderstood some things. Did you have rejections or was it the first submission?

Same here, (6782097197). Stuck 'In Review' since august 3. Before this I requested a consult by telephone but never heard back. Requested an expedited review yesterday but so far no luck. Also noticing a possibly related symptom: a new TestFlight build for the same app won't install for our internal tester (generic "could not be installed" / "app is not available" errors), even though App Store Connect shows it as "Testing" and the tester's Apple ID is confirmed correct. Ruled out device-side causes (restart, storage, network, reinstalling TestFlight itself). But not really sure if that is somehow related. Curious whether others seeing this have found anything that actually got a response from Apple, or whether this eventually just resolved on its own.
