It does work, however, something is still odd.
It was built F&D (fast and dirty), so I cleaned up a bit and noticed while testing with QML live, I got immediate results, like I had in the previous version. In that version I hadn’t set PositionSource active but had button to allow it. In any case, even without the button, if you had GPS on, you immediately got a list. Now, if you exit and start the app from the tray, agree to the Sailjail, (all the time, GPS is on, for instance), the view first needs to start (with NaNs) and you have to exit the view or hit the button and wait before you get results.
Something is broken. If I remove the Sailjail, it just works. The crappier code was snappy in 3.4. Now you actually see the Locate & Update button and wait for seemingly for ever. I mean. It does work. But it was better. More fun. Fluffy.
It’s pretty crappy code (well, a bit better now 
so I don’t expect help but maybe someone could confirm my observations? Maybe it’s a ports issue? Maybe it’s only Volla? Version 0.8.0 in the repo.
