Somtimes I get subscription details, sometimes I get error 3300, when asking for SubscriptionDetails
When using Taifun in-app billing, I get Error 3300. "Error 1 in extension an unknown error occured: The operation SubscriptionDetails cannot accept the arguments: ,[ nothing ]
You can see that is shows the arguments divided by a comma and the first argument is empty.
Still it is possible to subscribe, but I cannot show title and price before customer decides to subscribe.
I put already a 1 second delay between initialization and asking for SubscriptionDetails but that did not solve the problem.
When I have subscribed it always gives me the 3300 error when asking for SubscriptionDetails.
Update: Sometimes it gets the DescriptionResults on an Android 6.0.1 but on an Android 8.0.0 it always gives the 3300 error.
