Thank you for contacting Avenza Support! This would either be an issue with your device or the map itself. Can you send the map file to email@example.com, along with details about wether you were using WiFi, Cell Services or just GPS for your location, and if you can find your location on any of the Map Store Maps? With that information we can understand what is causing this issue!
Adobe released an update to Illustrator 2021 (v25.3) that includes native support for M1 Devices and Rotate Artboard functionality. Please note these features are not yet supported within MAPublisher at this time. See compatibility notes.
