Hi Kiyu! OK, that's a truly weird one. I have not seen that reported in the past. Do they just continue to scale, or do they stop at some point? Does this happen on every layer? Only marketplace maps, or ones you've uploaded? Does the behavior continue in a private browsing window or different browser? Sorry for all the questions, but this sounds new, and the questions rule out certain possibilities. For instance, more recent marketplace maps will now come in at intended size on the map layer. If you have a connection issue, this behavior might be impacted. Or it could just be the unintended consequence of a recent code push.
