It probably has more to do with the age of the device. I'm going through a similar issue with a Kestrel Windmeter firmware update. It was updated to 5700 Elite with Advance Ballistics functions. Now Advance Ballistics released Quantum but it's not recognizing I have an Elite device. Advance Ballastics says I need the latest firmware update but Kestrel says I'm up to date one version below the latest. I've submitted requests to Kestrel about why I can't update to the latest firmware but they are ghosting me. Seems if it is not their latest version they don't want to revisit the past.
