Yeah, the folder structure was the issue on mine too. Didn’t need to change the services.xml but if you get the folders wrong it seems to apply changes globally.
Anyway, this is still a bug that needs to be fixed as the glider support worker should always spawn regardless.
Fixed as above - thanks! Loving this update! 
yep - this fixed it for me as well… thanks for troubleshooting this!
Just do a win explorer search in community on:
services.xml
services.spb
and open file location for each and look for the incorrect structure. Took me about 10 minutes to find everything after reading this.
Thx!
Do you have the same issue if you follow the OP’s steps to reproduce it?
Yes
Provide extra information to complete the original description of the issue:
there’s no one holding the wing like i see on other people videos
If relevant, provide additional screenshots/video:
Microsoft force feedback 2
The suggestion with the service.xml helped me as well. Thank you very much. 
I just enjoy my first MSFS DG1000 flight.

I noticed if the runway you’re using isn’t long enough for the tow plane to take off, it will start the run but then stop when it reaches the end.
It looks like that is definitely the case and combined with me missing that there was an option to switch launch methods, doh, it appeared to count out certain runways.
All’s good now though, at least for getting off the ground, although the lower launch altitude provided by a winch might make flights from some airports far shorter.
Having this issue too - worked fine for me previously, but no joy now (and no-one to hold the glider is appearing). I suspect it’s a scenery add-on causing this, but no idea which (going to have to do a lot of trial and error!)
Same issue here: one mod airport I made to recreate a glider club nearby is stoping the town plane: it has the signal, push the throttle and pull back without even moving.
I almost deconstructed the airport piece by piece and haven’t yet found the issue.
Using no pedal here and testing without my Airbus Thrustmaster joystick. No issue with other airports, mods or not yet or by removing this airport.
I’ve been playing about with Addons Linker and it looks like there are several scenery mods I have that are causing this, so I really hope there’s a fix at the glider end that MS/Asobo can introduce.
Mmm.. no Services.xml or .spb file at all in the mod with the issue. I will have to start back to zero.
In any case someone has an idea, this is the gliding club airstrip that has the issue: https://flightsim.to/file/42546/csk5-paquet-airstrip
Had this issue myself , managed to get it sorted by logging into Flightsim.to and check for updates . One of the airports I had installed had an update from it’s developer that solved the issue .
Wasn’t looking forward to testing blocks of add -ons to try and discover the trouble maker 
I was also having this issue (no ground crew holding the glider wing was appearing and tow was not triggered) and I had to fix it manually. If you have any airports with a faulty AirportServices config that will override the world services globally at any airport producing the error everywhere (also regular ground services may disappear).
This is an old issue that started prior to SU9 if I´m not wrong. Airport developers need to fix their addons or users need to apply manual corrections as described above. As of today there are still several airports in Marketplace that have faulty services configs (most of them including just uncompiled files). I will create a topic on the third party section to warn about this.
Cheers
Feel free to contribute to the list of faulty airports:

In my case, I’m the developper of the scenery and can‘t find what is the issue that prevent the tow plane to start rolling.
On one runway end it crank the engine on then pull back the trottle. On the other end, it start rollinf a few feets then trottle down, turn right and stop
I’m using Steam and Thrustmaster joystick with rudder twist handle. Rudder does move on glider but no launch
Just out of interest, do you have the FBW FSLTL model matching stuff installed in community? I wondered if it was that?
