In my previous versions of Photoshop Elements, after I had added a reasonable number of images to Organizer - or had renamed a reasonable number of images so that they appeared 'new' in the catalogue - I would get an on-screen reminder when I loaded Photoshop Elements suggesting that it was time to create a backup.
Since I moved up to PE2020 (version 22.214.171.124), this no longer happens. Of course, I should remember to do regular backups anyway - but we're all fallible, and I appreciated being 'nagged' by the regular reminder.
Has this facility been removed in PE2020 or am I missing something in setup? Is there any way of restoring it, so I have no excuse for forgetting to backup? Thanks.
I'm using PSE 2021 so some things may have changed, but I'd check your settings at first. Press ctrl-k and then the first section ("General"?). At the bottom you should see an option which you can use to specify your backup frequency, but it also should have a button which allows you to restore all warnings.
Now, I'm not 100% sure but I assume that this will also restore your backup warnings.
