I don't want to be notified of the generate fill feature ever again.

Every time I start up Photoshop, I get an announcement appealing for the addition of a generated AI function, which is very annoying.

I have no need to use the generated fill function in Photoshop because of the type of work I do, and it is extremely annoying to have to delete the announcement every time I start Photoshop, or to have to open sample files without my permission.

It must be a bug if you can't prevent this dialog from appearing again.
