Trying to test IAP in sandbox. I created the test group and tester accounts. Accepted the invite downloaded the app. Signed into to sandbox in settings with the tester account. In app the purchases are failing and throwing my catch error message product couldn't be found. I decided to test it from settings/ sandbox/ manage/ initiate purchase/ but I've been getting "can't complete transaction. Something went wrong, ant this transaction couldn't be completed. Try again later" since last week. I reached out to dev support over the phone then email and they couldn't or wouldn't provide assistance. I asked my senior at work she took a look at it and confirmed I created the IAP correctly and that my sandbox account could make test purchases in apps she make but couldn't get mine to work. The storekit test work fine in xcode I just don't know what to do now.
