EDIT: I opened the game today, the day after making this comment, in Windows, the same download as before, and the bug is gone. The routes in the Maps popup are now clickable and I can move. I don't know what happened, but there doesn't seem to be an issue anymore.

ORIGINAL COMMENT:
The Windows download version of the game has a bug. I can't switch maps. I click the Maps button to see the routes, and the other routes are unlocked, but not clickable. I tried on the web version on pokepath.gg, and I can immediately go to the next route once I get 10 stars. I have 96 stars from the first route on the Windows download version, and the next route isn't clickable in the Maps popup.
I downloaded the Windows version on Feb 13th. So this was after the latest update as of writing this comment. Would love a reply from you when this gets fixed, so I get notified to download the latest version.
