Hi Naomi, I hope you are doing great!
I am working on it as we speak! One of my beta user was able to buy coins and restore the ad-free version (which I bought earlier using the same test user) I have sent him a new tester user info as you suggested earlier. Waiting for that result. Another beta tester is not able to use that same tester user (the one I already used) and the message saying he is not authorized to make a in-app purchase in the sandbox Not sure what is different so tonight i sent that beta tester a new test user that was not used before.
I guess for beta testing with many people, it is best to send them each a different test user login info that were never used.
Thanks again for all the suggestions here. I appreciated.

ps: By the way, how do you deal with multiple product restore. Thank God I only deal with one product restore (ad removal) but my understanding is that the store send back something for each product. How do you differentiate between the multiple restore in the callback? Just curious for the future…
