Lucky for you, it works for you, but not for me.
I have over 15.000 pictures running, I am changing my theme and moving to another server, so I have to rebuild many pages and also the galleries. Can’t take over the old gallery, because the old theme can’t be changed, WordPress won’t work anymore.
To get back to the gallery… It’s the same problem as described above and I have disabled all plug-ins except one!
Only Gutenberg works fine, unfortunately it’s not an alternative for me, because my pages run with WP Bakery.
Wordpress is version 5.5, PHP is also up to date.
