Hello,
I want to switch my license from a test site (ggg.amtenbrink.de) to the final site (ggg-web.de) but after filling out the form with my license code nothing happens, even after 20 minutes. License on the old site is already deactivated in my account.
No worries, I have manually changed the domain for you, it should be visible on your products page too. No further action is needed at this point, if it asks for a license it should automatically see the correct domain.
In case of any issues, please add temporary back-end login and (s)FTP details and I will take a closer look.
