I’ve found a quasi work around because I’ve been having this issue for TTT’s where I use the Zwift Ride and need the virtual shifting but have teammates that don’t have steering and as a result don’t smoothly follow my avatar when I have steering enabled. So this is what I did and it seems to have worked. Turn on zwift, pair bike and controllers. Start a free ride. Since the controllers are paired the gear ratio shows up on your screen (it doesn’t if you start riding without pairing the controller). I then turned off the controllers and then opened the pairing screen. The controllers aren’t connected because they are off. I exit the pairing screen. Gear ratio is still visible on screen but handlebars aren’t beside my name indicating that steering is disabled. I turn the controllers back on but don’t open the pairing screen. For some reason the shifting has reconnected but the steering hasn’t. Do not open the pairing screen again or the steering will reconnect. Also of note my controllers won’t actually both turn off when the bike is paired but they do reboot if you hold the power down like you are turning them off. Seems like the key is opening and closing the pairing screen when the controllers are in that few second rebooting state. Hope that works for you as well
