Im also having this issue. I'm unable to clear my purchase history.
After 13 renewals does an account somehow expire or is unusable? I'm unable to clear the history on it. I don't want to create new email addresses every time I want to test.
I think there may be a separate sandbox account for each new build. I signed out of my sandbox so that the subscription purchase works. It signs into possibly a new sandbox for the new build.
Is this happening in testflight or production? I've had something similar happen, when I signed out of sandbox the transaction finally appeared in the app. I think there needs to be more attention to this.
