Thanks, I checked subscribing with my device and works, as long as I’m not running the storekit test environment. So I guess it’s just a dev. thing.

One thing that helped me was to set up the StoreKit Testing Framework section in RevenueCat.

The description implies that this section is only used for automating Xcode testing, however it is also required for any manual sandbox testing too!

See this guide:

https://www.revenuecat.com/docs/apple-app-store#ios-14-only-testing-on-the-simulator

I’m setting up this up now to work in my project and am getting this error. Is there any resolution or is it still being replicated by others? 

This is happening to me too, as described above.

ERROR: Product purchase for '#####' failed with error: Error Domain=RevenueCat.ErrorCode Code=8 "The receipt is not valid." UserInfo={NSUnderlyingError=0x600003718e70 {Error Domain=RevenueCat.BackendErrorCode Code=7103 "The receipt is not valid." UserInfo={rc_backend_error_code=7103, NSLocalizedDescription=The receipt is not valid.}}, source_file=RevenueCat/HTTPClient.swift:699, readable_error_code=INVALID_RECEIPT, source_function=parseUnsuccessfulResponse(), rc_response_status_code=400, rc_backend_error_code=7103, NSLocalizedDescription=The receipt is not valid.}

In a physical device there is no problem for me it work without a problem but I cannot make a test purchase in simulator. I recieve this response The receipt is not valid.

Probably there is a reason for that but habe idea to be honest.

I started to get this error around 2 weeks after the integration.

When I run it on the device with a test user added I started to get this error.

I’m on Unity where I never got such an error with Unity IAP, but revenuecat is always gave headaches. 

I assumed I don’t need to set up Storekit testing because I’m on real device. Right?

Hope they will resolve it soon ! :) 

Signing out and back in with a sandbox account worked, but logging in with my iCloud account on TestFlight still did not work!  I know behind the scenes Apple makes a Sandbox account for TestFlight users, how can I force it to log out of that account to fix this issue?

Update: Apple’s reporting the issue is fixed, but we’re still encountering errors. Will provide another update as soon as possible.

For me, it is working 

im still facing this error untill now  , are you happy now ?

I’m located in the US. Not fixed for me yet. 

More than happy !! 

It just started working !!! 

@cody What’s the appropriate behavior of an app if it encounters a “Receipt Invalid” response during a purchase?  Not only is it showing “Receipt Invalid” but looking up entitlements in customerinfo shows an empy list, and that’s how my app checks for a subscription.  Does this mean that during this issue there is no way to check if a user is subscribed, or is there a workaround?

I just tested via TestFlight with a real icloud account, I’m still seeing the issue, getting receipt invalid after a purchase, entitlements return empty from Revenuecat, if I try to purchase again it says already subscribed.

I was able to make a consumable and sub purchase in the sandbox for the first time since Monday night.  I did it on my iPad. When I did a restore purchases attempt on my iPhone I got the same invalid receipt nonsense I’ve been getting since Tuesday BUT when I backed out of my purchases view the app recognized that a sub was valid and adjusted accordingly. I’m just glad things are back to normal so that I can keep developing.

For me it is still not working, I am trying to buy a subscription in sandbox mode (testflight) on iOS.
 

Thanks @Chris-29 my subscriptions are working now.
Hey @Dylan Thomas and @user9837291 try the @Chris-29 `s solution.

im seeing the issue still. some folks here suggested logout and login  of sandbox. is that the browser login ? or SDK ? is there a thing like that on SDK ?

Try creating a new tester account

Hi! Worked for a few hours and the problems started again. Is it really so? The Apple page says that the service is working properly, but I started getting sandbox errors again

update: worked again after several attempts, without changing anything

I still have the issue with a StoreKit config file and iOS simulator. Are there any updates on this issue?

I'm trying via testflight and it's working correctly, I haven't tested it with StoreKit

Still seeing this on the most recent version of the revenue cat SDK (react native js). This is not an issue production at all? Only in testFlight?
 

I’m getting this today as well
