Hi all,

After doing a lot of troubleshooting and some frustrating moments. I was able to fix it (for now).

So I was searching various topics and found an old topic (2022) where someone mentioned a wrong wheel-size in the Wahoo fitness app had impact on the resistance in Zwift. This person said everything worked well after resetting the wheel size.

I’ve thought to give it a go and did the same thing:

- Reinstalled the Wahoo app
- Added the Kickr Core
- Went to the settings
- Changed the wheel size from the default (700 18C) to 700 x 19C
- Performed a spindown

After these steps, I opened Zwift and connected the Kickr Core and Zwift Play… and everything worked as expected on my tablet.

I will try to use Zwift on my laptop later today to see if it works on my other devices.
