The problem is that purchasePackage takes long time (over 60 sec) to complete its job and return value. Developed with Flutter, testing on iOS device with Sandbox environment.
The related code is :
CustomerInfo purchaserInfo = await Purchases.purchasePackage(selectedPackage);
Is this something related to Sandbox and App Store Connect and no need to worry on production environment? If anyone advise on this issue, ,much appreciated. Thanks.
