I had v 2.5 on my watch and everything was great. Since then on 2.72 or whatever it jumps around like all the previous optical monitors did. The 935, Vivoactive 2, Fenix 3. Why did you guys screw it up?
It's messing up every single piece of data now and making my watch unusable. My RHR should be 44 as I type not 80-100. Same as a run. I know this for a fact. I measure it myself.
Now I'm upset. How can I fix it so I have v 2.5 and never ever ever ever ever update?
