Where does one get the "shared secret" from?

Next time I have to work with app store subscriptions I'll just let the client know it will take 9 months and $200k. Sandbox is broken half the time, and when it does work it returns nonsense results like saying a subscription just purchased is already expired.

Same problem here. Clearly a bug on Apple's side... who knows if it only effects Sandbox or will also happen in production. Of course Apple never replies here, it's a waste of time.

Can confirm -- sandbox behavior is extremely erratic and unreliable. Some days it works, some days it doesn't. Some days it will auto-renew, some days it doesn't.

Sandbox behavior seems extremely erratic. Sometimes it will renew a few times then cancel, sometimes it won't renew at all.

I'm having the same problem after upgrading to XCode 14.3.1 (14E300c). I'm not trying to build for WatchOS nor the simulator so I don't know why this "Extended Platform Info" stuff is even involved. 2023-07-03 09:50:50.698 mlaunch[57625:1559747] Thread Pool Worker DVTAssertions: Warning in /System/Volumes/Data/SWE/Apps/DT/BuildRoots/BuildRoot7/ActiveBuildRoot/Library/Caches/com.apple.xbs/Sources/DVTFrameworks/DVTFrameworks-21780/DVTFoundation/DeveloperStructure/DVTExtendedPlatformInfo.m:79 Details: DVTExtendedPlatformInfo: Synthesized iphonesimulator Extended Platform Info because no plugin existed to provide it or that plugin was not loaded Object: <DVTExtendedPlatformInfo> Method: +extendedPlatformInfoForPlatformIdentifier:error: Thread: <NSThread: 0x600002582e00>{number = 10, name = (null)}

Having the same problem. Trying to build a Xamarin app so possibly related issue at https://github.com/dotnet/maui/issues/15542
