What browser are you on? Is it a big gallery? I just made some in mine to test and they saved and showed up immediately.

I know it's been a moment, so I wanted to check in if you are still noticing this? When I tested, I did it in a shop with only a few categories/items.. wondering if that's why it worked right away and didn't get stalled in a cache or something.

Glad to hear! I'll lock this up as resolved.
