Threadmill running distance not recorded

[cleoleeps]

My 9PP used to be able to record how long the distance I’ve run when I used threadmill. But it didn’t capture properly since Jun 2024. The GPS is already turned on and off for threadmill mode but doesn’t help.

I should be running like 3-4 km after 30 mins but it recorded like less than 1km.

What is missing ?

Is there anyone having this issue too ?
