The upgrades are ruining a perfect product

I love my Mi band. Used it for more than 1 year and bought more than 10 for friends and family. Then came the upgrade to 2.0. It cant track my sleep any more with no benefit!
I am a fan of Mi products and have many gadgets from Mi. This upgrade is going to force me to something else.
Please fix it!
