Companion app no longer seeing power, cadence or HR

Hi guys. Since yesterday my Companion app will only pick up and register my trainer as a controllable device (ie bottom right icon), it is no longer seeing it as a power / cadence sensor and also not seeing my BLE Hr sensor.

It is definitely a Companion issue because if I link directly with a newer laptop with BLE built in it sees everything as usual (but this is a work laptop so I can’t use it as a regular solution). Anyone else having this issue? I’ve tried deleting and reinstalling the app, repairing all devices with my phone, installing Companion on my iPad and even an old android phone - same problem. The phone / iPad is seeing the devices (ie in Bluetooth settings) but not Companion. Help!!
