I purchase f 16 its not valid but i have evdence
Can we see a screenshot?
Is it possible to pls. give us device and OS inofrmation? Devscan’t fx your issue without more info. :)
This should really be under support, in my opinion anyway.
I don’t understand? Please provide more detailed information including device make and model. If you have completed a purchase, you only need to install. If the install fails, depending on why or if an error message pops up, restarting device power and trying again usually resolves the problem.
