SOLVED - New MacBook Air M1 won't recognise ANT+ dongle and HRM - Help please

Hi all,
I have recently bought the new MacBook Air with the M1 chipset 2020 running Big Sur
I have a Elite Drivo connecting with bluetooth along with a Garmin HR strap ANT+ and use an ANT+ dongle to allow the TR app to connect. The dongle connects to the Mac via a cable to go from USB to the new port on the latest MacBooks.

I simply cannot get the ANT+ to be connected using the new MacBook Air… shows as off in the app.
To test whether it was the HRM or Dongle that had the issue I used my work MacBook Pro (2019) and it all works perfectly…

Anyone else had similar experience with the new M1 chipset MacBook Airs? Anyone resolved the issue?
I’m at an absolute loss what to do now

Thanks in advance,
Bryan
