Hi, I have exactly same problem with my app. Subscription just keeps renewing every day for already a month. First I thought that it would stop in couple of days but I don't think so. Also, my app is macOS based and there is literally no way to see or managed the subscriptions in sandbox for this kind of apps. I found temporary workaround – logging in with a different sandbox user. However, this is not covering all test cases I need to check. This needs to be addressed soon please!

Turn off User Script Sandboxing is an easy but not the good answer... Many apps still need to sandboxing for setting up crashlytics, build numbers, etc. Is there a way how to fix this without turning it off?
