I went to do some gliding yesterday and I no longer have a wingman and can not get the tow plane to move by wig wagging my rudder. Any thoughts? I have assistance on for airport vehicles. 

Found this months ago:

Towplane/Winch Reminder: Both MSFS 2020 and 2024 have a known bug when launching with a towplane or winch from your chosen airfield. To avoid it, make sure ATC Enforce Flight Plan is Enabled in your Assistance Settings. This forces the towing vehicle to spawn correctly with your glider. If it’s disabled, you can get a desync between the glider and tow vehicle — the towplane may refuse to take off, veer off the runway, or the winch may even spawn behind you. This is a base-game issue, and Asobo/Microsoft are aware and working on a fix for a future update.

Hope you can fix it with this.
