Hello - I am having the same exact issue. Once INTERRUPTED SERVICES is checked and saved, it very rarely will accept an uncheck and save. I have seen a coupe of my sandbox testers uncheck, however, the vast majority do not. They remain checked.

Hello - yes, I am still seeing the same thing. The way my app works, is when you get the accepted agreement, it return to the window which shows the error from the failed transaction. Once the user goes back, a restore transaction is called (I do this every time on my Home screen) and it picks up the transaction. It's ugly but t works. I saw in another post that unchecking INTERRUPTED PURCHASED for the Sandbox user JUST BEFORE accepting the agreement allows the final purchased transaction to trigger, however, I am seeing an issue where unchecking that box in App Store Connect does not always save (which I just filed an issue for).
