We have an app that’s build in Flutter, and it works with both Play Store as well as Apple Store. On both platforms we have set up products (no offerings, or entitlements), as the approach is that the users can buy a product (subscription) and change it at any time.
The Apple Store subscriptions works well (in sandbox mode) and I am able to buy the lowest subscription, then upgrade to higher, and finally downgrade again, without waiting for a subscription to expire.
On Play Store, however, this doesn’t work. I start with the lowest subscription, and then I can upgrade, but if I tried to do another upgrade/downgrade, I get Play Store popup with the following message:
Error retrieving information from the server.
DF-DFERH-01
Then I get an error from RevenueCat SDK:
PlatformException(2, There was a problem with the Play Store., {code: 2, message: There was a problem with the Play Store., readableErrorCode: StoreProblemError, readable_error_code: StoreProblemError, underlyingErrorMessage: Error updating purchases. DebugMessage: . ErrorCode: SERVICE_UNAVAILABLE., userCancelled: false}, null)
Only once active subscription ends (expires) am I able to change subscription.
I should also point out that when making a purchase, I am setting “Immediate with Time Proration“ mode since I saw on this forum that Android only supports that Proration mode. Regardless of it, it always gives me the same error.
What I’d like to ask is if there is any way I can make Google Play Store subscription to be changed at any point (downgrade/upgrade) so it doesn’t give this error? Am I missing something in the subscription configuration perhaps?
