Just when I thought I could get rid of foogallery plugin and use the built-in Oxygen gallery, boom, screwed again.
So the gallery > layout > Images Per Row DOES NOT SUPPORT MEDIA QUERIES!!
I have a gallery with 4 per row. Look at it on mobile and it still shows 4 per row. Change it to 1 per row while working with the 992px breakpoint and it applies 1 per row to the All Devices breakpoint. So now the desktop view is showing 1 per row!
Come on guys. The gallery feature has been screwed up for so long.
This was reported as a bug on June 6th, 2020. It was, for some unknown reason, marked as closed. There was CSS provided as a stop-gap but you know what, that CSS does not even work!
