Hi there
Thanks for getting in touch!
Sorry to hear you’re experiencing this issue.
Are you viewing in portrait? Because portrait has a different aspect ratio, you wouldn’t see the edges of the polygon.
There are two possible solutions:
1) Zoom out one click on the map editor and save
2) We can add some Javascript to the site to zoom out by 1 on mobile devices upon load
If you’d like to go with the latter and need code, we can provide that for you if you need?
Kind regards
– Perry
