Why is the Generative Fill button greyed out if I'm over 18?
If you find that Generative Fill is greyed out for you and you're over the age of 18, it is possible that you may not 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:
Click "Check for Updates" in the Beta apps section of the Creative Cloud desktop app to check if there's a new Photoshop (beta) app build available and update to build m.2196 or later.
Sign out and sign back into the Creative Cloud Desktop and Photoshop (beta) apps.
Log into Behance with your Adobe ID and enter your Date of Birth.
If you sign in using social sign-in (Apple, Google, and 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.
If you still have trouble, contact Adobe Customer Care by Chat or by Twitter:
