Over the past week I have already encountered several times that the user pays a purchase in the application, but no additional content is activated.
Began to understand, it turns out, sometimes Google gives for activation up to 24 hours. It is not clear from what considerations.
On the other hand, many purchases are still made instantly. I use the standard (proposed by Google) system inapp, which was a year ago, a typical code.
Actually, the question is: has anyone encountered such a problem (lately)? You may need to make some changes to the inapp code.
I found some new way to billing in Google. Is it typical, mandatory and impossible to work with previous versions?
