I’ve been having this problem too and, as weird as it is, this is what I have found that works: I try several different styles in map styles. You get a preview map and keep trying to move the preview map. Keep trying different styles until you get one that allows you to move the preview map. When you go back to your comp - regardless of what style you ultimately choose, - it’s fixed. I haven’t experimented enough to find out if there’s a particular map style that does the fix. But the last time I did this it was the Map Tiler administrative boundaries made it work. I know this is just a really weird workaround, but it’s the only thing that’s worked for me.

Hi Joel, I'm still having this problem. My "fix" is no longer working. Have you discovered a solution? I've written Nico a number of times and they are responsive but have not come up with a solution.June 2023
