Sense says couldn't read SpO2 data

[Valleyboy22]

Hi.

Bought a sense and installed the sp02 on it.

Had it on for days not and it says its recording in the morning when I get up and then says couldn't read Sp02. Getting a little frustrated now to be honest.

Any help on this please.

Mine was working fine for about a week...nothing changed and suddenly now I am getting "couldn't read spo2" on the face. Every day, I become more disappointed with my decision to purchase the Sense.

Bloody joke

Been told by fitbit to put it on my other wrist when in bed. We will see

For some reason, my SP02 is always a day late - and sometimes doesnt show that up either till several hours after I get up
