Running on windows 10, with a Tacx neo2 trainer, connecting over ANT using a usb dongle.
Issue is that my neighbour also has a Tacx Neo2 in his garage and I think sometimes leaves it switched on when not in use.
When I launch Zwift, zwift sometimes, but not always, connects to his trainer as the controllable instead of mine (although it always manages to correctly connect to mine as power and cadence). If I spot this before the pairing screen goes then I can manually unpair and pair mine, and it’s ok, although a pain, but sometimes I’ll be busy sorting other stuff out (water, fan, towel etc.) And the screen will auto close, and I’ll start riding and belatedly realise the trainer isn’t being controlled by zwift.
I have tried deleting the known devices and Prefs files multiple times, but it still keeps happening, so it seems Zwift has stored on a server the fact that I must have connected to it once in the past and is for some reason syncing back when the files are recreated.
