I am testing the demo version.
I can successfully complete a sandbox purchase and the role I have set in the configuration is successfully added to the user for a period of 30 days. This behaviour is correct and as expected.
However, if the user then makes a purchase again, i would expcet the role expiery to be then 60 days (30 days from the previous purchase + the new purchase). but this does not happen. No matter how many purchases I make, it remains at 30 days (which was the first purchase).
Is this a bug or am i missing something ?
