Multiple attempts to add my work G-Suite account to the Pro yield the following error message.
Encryption must be enabled on the device.
Touch to encrypt
When I touch the watch face to encrypt, it just goes blank and resumes operation, but the error is not dismissed and recurs periodically. I assume the watch does not support a device policy that requires encryption? That would have been super helpful to know before I blew a big wad of cash on the watch.
