In Testing Mode, When a subscription has expired after its duration or if I cancel manually, and try to buy again, It always returns status code 2. Even subscriptions are purchased. Subscription purchase successfully dialogue will shown. Purchased subscriptions are displayed in the Google Account subscription list.
Sometimes I got status code 0 as well. I don’t know why I got status code 2 and the error:
Server error, please try again.
