Very annoying bug with challenges

I'm now doing the raid pyrenees challenge with the productive version. Some days before I did the first 10,1 km of raid 6 (Marie blanque). Yesterday I did the rest of Marie Blanque (17,1 km) and directly 6.5 km of raid 7 (Aubisque). During the ride of the aubisque I was wondering why the climb pro control shows the Col de marie blanque (see picture below).

That are my save activities:

But today I had to do the rest of col de Marie Blanque again, because the challenge has'nt recognized it.

So I would recommend to save each finished stage  ride during a challenge and not starting directly the next stage.

  • Had the Tacx App on my phone, not active.
    Was running the Tacx App on my iPad in continous mode, on a Tacx NEO Bike Smart, also doing Raid Pyrenees.
    Had several problems like yours.
    Turned off Bluetooth on my phone while training, and all problems disapeared.
    Think the the phone graps the trainer when the app on the iPad is shifing movies.
    ( My wife on same system, never having installed the Tacx App on phone or computer, had no problems ... )
