TB18-2 temperature offsets and FW update from 1.21 to 2.0

Hello,

When I click the button to update my TB18-2 in the admin app an error shows immediately "Update Failed" without any error code.

Moreover, the app stops responding at this step. I have to close and restart it to perform any further actions.

The current FW version is 1.21. The app is telling that there is a 2.0 version available.

The device was purchased just recently, I've got the shipment from Kontakt.io just yesterday.

I don't see the option to input the temperature offsets. So, I wonder if a FW update can fix this. There is a ~4° bias I need to calibrate.

Best regards
