You are not authorized to make purchases of this InApp in Sandbox at this time.

I see the same.

Didn't find your question and created new one in the Framework's

Thanks for sharing.

It suddenly stopped working for all my testers without any action on my side.

We're 100% it's Apple, now !

I see the same.

I've spent hours of struggle due to this issue.

Also having the same issue! Was working perfectly 5-6 days ago

Same issue here!

No workaround / solution found yet.

Yup, I'm seeing the same thing here. Started ~2 days ago, and still doesn't work. Anyone see any movement from Apple on this issue?

I can confirm that the live version of my app is still humming along just fine in regardes to IAP being purchased successfully.

I see the same problem.And I can not find any solution.

Same for 2 days - filed a bug report this morning

➕

I filed a bug as well.

Update : it STILL doesn't work

Same - Thank god I'm not alone.

I've been talking to support and they said raise a technical support request (that would be a waste!).

I'll send them this forum link so they can see this needs action.

I have found though

It doesn't matter if the email is an appleID or not - it still fails in test flight

It doesn't matter if you uninstall/rebuild/reinvite - it still fails.

I tried an account that had been setup as an original sandbox tester (pre-testflight) and it WORKED in testflight.

Your last sentence can be the answer. Maybe, only the sandbox testers will have possibility to buy. Sorry, that I said that. 🙂

It's still a massive problem if you can't use external testers in TestFlight (as testflight was designed to do).

It's been fine up until a few days ago.

I've tried making noise - please make more!

How can I use a internal test account to purchase in sandbox?
