Horizon gr 7 ble connection racing start times

Hello,
I have a question relating to Team Time Trial racing on ZWIFT and the trainer i use, which is a BLE connecting HORIZON GR 7 Indoor cycle.
I recently signed up to a team to take part in time trial races, and have come across a problem at the start line when waiting for our team start time to elapse.

The issue is, the BLE is activated by pedaling the bike. When i join the event i have to start pedaling but then stop if and wait for our start time.
I found that the AVATAR Stops as required, but when i began to pedal again, the AVATAR will not move and the BLE connection appears to drop out.

I have tried pedaling backwards, but the AVATAR still moves forward.
Does any one have any advice or has experienced a similar problem?

Thanks
