hi, thanks for your reply! It took so long to hear back from anyone, that I went through a zillion different gallery plug-ins to get it to look right. In the end I ended up using the Jetpack tiled gallery mode, instead of the Gutenberg gallery block. That solved the problem and that’s what you already saw on your mobile screen. If you’re curious to see what the broken one looks like on mobile, check out my wordpress.com version of this site, where I didn’t repair the issue:
