Why is Photoshop thinking, that i'm under 18? I searched for 30 Minutes in Cloud-Account and on Adobe.com, but found no way to set the birth date or something.....
The new function Generative Fill is greyed out and you get a warning that you apparently to young even though you are over the age 18. In this case it is possible that you don't have a valid Date of Birth associated with your Adobe ID account.
To update your Date of Birth, you can do either of the following steps:
Sign out and sign back into Creative Cloud Desktop Client and Photoshop (Beta) app
Log into Behance with your Adobe ID and enter your Date of Birth.
If you sign in using social sign-in (Apple, Google or Facebook), ensure that your Date of Birth in that account is set to public instead of private.
Once your Date of Birth is up to date, relaunch the Photoshop (Beta) app to enable Generative Fill.
