Now I am login apple using a new sandbox account, when I am using in app purchase. It still using the old account. I have tried:
close the app and reopen it and do in app purchase, but still popup UI using the old sandbox account
reinstall the app and do in app purchase, but still using the old sandbox account
tried in another ios device(iPhone XR) using the new sandbox account(the app still using the old official app id)
what should I do to switch to the new sandbox account? By the way, I am using iPad, and the software version: 14.6.
