Wahoo bolt 2 - elevation indoor ride, incorrect speed

i train on a wahoo kickr v5 and bolt 2, since july this year i have noticed and the speed of my rides varies a lot and suddently slow to a walking pace on the wahoo unit when riding indoor, and later find that it would display an elevation dispite it is set to indoor, the speed would depend on the whatever elevation it decide to produce that day.

i have been in touch with WAHOO support since early july, initially they suggested it was a buggy unit, and was offering to send a new unit to try (wahoo bolt 2) around mid/late august.

then as soon as they confirmed a manager stepped in a week later to say it was a know software issue and then Wahoo dropped off the cliff and stopped replying.

around the same time auto upload to training peak, work out update syncing with training peak require a manual disconnection (and it infact does not disconnect) and try multiple times before it would sync workout onto the bolt or upload.

these issues are yet to be resolved and its now 4.5 months since i first flagged it with wahoo.

anyone else with the same issues?

@kirk_kwok TP sync is working for me and there is a page in settings in the Wahoo App to deauthorize and authorize and the process is straightforward.
