When I update the map, I get the option where to install it with a radio button: device, pc or both. Garmin Express v4.1.21.0 shows this radio button, too.
But: When map is already installed on device only, I normally had the possibility to install it on pc afterwards with a second button "install on pc" in window "map options".
Since v4.1.21.0, this button is missing!
To install it on pc, when it's already installed on device, Express says it's all up to date and I only have the option to reinstall it on device (with no target option).
A workaround is, to delete it on device and install it with the "both" option. But this takes a lot of unnecessary time.
Downgrading to v4.1.19.0 "fixes" the issue...
Did you remove the option intentionally??
