Ok,
I got it. So either i already had a trial with 21 days already running - there is 18 left. I tested one time my app before setting my app trial time to 0.
Is there a way to set trial remaining days to 0 or I have to wait 3 weeks to test it again ? Guess I'll test it in a virtual machine.
Also, when going from trial extension to activation. Do I have to "deactivate" the trialextension, or the activation just overwrite it ?
Thanks.
