I swapped my showcase thumbnail image for a GIF and it’s no longer showing up in the showcase. It looks fine in the showcase edit page.
I did some testing on this end with a GIF thumbnail preview and it looks like it works as expected.
Can you send over the GIF file you are using? Thanks in advance!
Thank you @Brando!
Looks likes GIFs compressed with ezgif don’t work in the showcase. I compressed it again with gifgifs and it’s working perfectly!
