Coospo H9Z HRM doesn't automatically turn on when I snap the device in the strap after 2 months of using it
I use it mainly during jiu jitsu sparring. First few weeks, it was working without issues but recently, it's super inconsistent that i ditched using it last night.
I already tried the key method, cleaning the metal contacts with alcohol, etc
Not sure what else i need to do. I spend almost 10 minutes just trying to set it up before my workout session.
And yes, i always make sure the strap is wet/moist.
