In the simulator (SDK 8.3.0) the Settings > Font Scale is grayed out for these devices:
fr57042mm, fr57047mm, fr970
even though according to https://developer.garmin.com/connect-iq/api-docs/Toybox/System/DeviceSettings.html#fontScale-var fontScale is supported.
(For d2mach2, fenix843mm, venu441mm, venux1 it's there)
Haven't tested the rest, to leave some fun for Garmin as well.
