I am using this version
purchases_flutter: ^8.1.0 purchases_ui_flutter: ^8.1.0

My app is live and I am generating a lot of subscription using the revenue cat SDK but I have a serious problem, there is a bug from the SDK happened more than 150 times in the last 28 days. You will find attached a screenshot.

This crash only is more than 85% of all the crashes happening in my app which increased the overall bad behaviour threshold for my app to 4%. The recommend by Google is 1.09%. As an impact my app will be less discoverable on Google Play. You will find attached a screenshot also.

You will find attached the stack trace

I am not sure but I think this crash happens when the user open the paywall and put the app in background and I believe that my configuration is good as I have more than 100 subscriptions.

Please it is critical bug and I saw many developers are complaining about it . Thanks

Hey @arshavin2000!
Thank you for including the stack trace. I'm seeing this message in the logs: "There is no singleton instance. Make sure you configure Purchases before trying to get the default instance."
It looks like this may be occurring when you're trying to display the paywall prior to configuring the SDK - can you make sure that you're calling configure just once, and early in your lifecycle, before using any other Purchases methods?

Hi @kmurphy-rc,
This is my function to configure the SDK.

`Future initRevenueCatSDK() async {
try {
await Purchases.setLogLevel(LogLevel.debug);

PurchasesConfiguration configuration;
if (Platform.isIOS) {
  configuration =
      PurchasesConfiguration('XXXX');
} else {
  configuration =
      PurchasesConfiguration('XXXX');
}
await Purchases.configure(configuration);
}catch(e){
debugPrint("PurchasesConfiguration error $e");
}
}`

and I am calling it just one time in Main.dart in the main function.

I guess it is the right implementation right ? I saw in some issues here that some guys succeeded to reproduce the issue by making the app in background while the paywall is open. I tried to reproduce it the same way on my device, I didn't get the crash but I got a loop when I close the paywall it opens again automatically.

Thanks to investigate more on this issue.

Here I have exactly the same problem in version 8.3.1.

Hi guys, any update for this issue. It is really killing my app , it is less discoverable now in play store due to this crash.

[arshavin2000]

Hi everyone, it has been over a month without any updates from your side. I'm seriously considering migrating to a new solution, like Aphid or a similar alternative, due to the high number of bugs related to this issue
