Erg mode disabling

Hi, erg mode keeps disabling on my Wattbike on Zwift which is frustrating when I’m doing intervals.
Can you ■■■■ with this? I’ve got the latest version of the firmware in Wattbike

try uninstalling and re installing software and ensure you have the latest Zwift updates and maybe reinstall then as well

How are you connecting? Ant+ / Bluetooth?
What devices are you using? Apple TV, Pc etc

Your not trying to run the the wattbike hub & Zwift both through Bluetooth or anything like that?
