Balance 20X - Firmware 8.5.2 & 8.5.3 - "RemoteSIM component is incompatible " Error

Hi all

I have a Peplink Balance 20X.

Firmware 8.5.1 loads fine with no issues

Firmware 8.5.2 & 8.5.3 both have this error: “RemoteSIM component is incompatible to the firmware, please contact distributor for support”

Is anyone else experiencing this?
