I have integrated RevenueCat for in-app subscriptions and it works correctly on Android. However, I am encountering an issue on iOS where the app returns an error related to an invalid receipt during the subscription process.

Previously, the subscription worked fine on iOS, but today it started showing the following error:

Hi @arundevops47,
Is it something that happens constantly or only a hiccup? Since it happened only in sandbox it could be a temporary issue on Apple servers.

I think it happens sometimes. Now it is working fine.
