Focus/Strain IQ app

i’m experiencing an issue with focus – Strain app on my garmin.
While the strain has a progression the focus is always without any number, but when i finish the workout, i can see the focus on the website.
How can i solve it? Anyway Xert is amazing keep it up!!!

Double check your Xert Code is correct. You can see that it is working correctly but doing a hard 1 minute effort when you first start recording. Focus should start showing a number. (Let us know if it is just showing in yellow… this might be some other issue…)

I said as you told and now everything works perfectly. Thank you
