New Meetup Bug

Well, the rubberbanding had been broken but now seems fixed. But yesterday, I scheduled a 2 hour Meetup with a friend (we do this once a week), doing Big Foot Hills. Everything started great; we rode together, only saw each other (which were my choices) and all seemed good. But then when we hit a climb, we both noticed that our trainers weren’t registering the gradient change. I have a Tacx Neo 2T and my friend has a Wahoo Kickr. Also, when my bike ran over the board plank section, my Neo 2T didn’t register them either, though on group rides earlier in the week everything worked perfectly.

Is this a new bug? That it happened to both of us, on different trainers, makes me wonder.
