why does my distance not show up when i go to zwifters on the companion app

Can you post a screenshot of what you are referring to.

it is where you can see the other zwifters and shows name country and wkg

He talks about zwifters tab. I have there always 0,0 km distance. Thats bug from long time.
For this i using map or dashboard tabs where whole distance is showed.

that is exactly what im talking about

Just use other two tabs (map and dashboard) and you will see distance and other stats like watts, rpm, speed and hr.
Some day zwift programmers will fix this on zwifters page too.
