Is Firmware rollback to 0.0.36 possible from 0.0.38?

Pairing via Bluetooth to Zwift (on Windows10) has not been possible since firmware upgrade to 0.0.38 on my Neo 2. Extensive troubleshooting with advice from Zwift has not resolved issue. 

Tried connecting Tacx to Zwift on a different computer today (MacBookPro). It would allow for controllable to connect via Bluetooth but it was behaving strangely (like having ERG mode on during a race). 

Hoping to rollback firmware to avoid these continuing issues please!
