Thank you for your post. Currently the Avenza Maps app does not provide this service, but I can create a feature request so our teams can look into it. I have gone ahead and added you to the feature request regarding “Automatic cell coverage mapping” so you will be notified on this forum, when the feature is implemented.
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.
