This app worked great before the update earlier this year. No issues. Now it constantly disconnects itself from my phone and I'd have to disconnect and reconnect every time; It tells me to allow notification permission when permission is already allowed. Additionally, most times it doesn't collect any sleep data and when it does, it's incorrect or it's recorded for the wrong day. I love the watch and I want to keep using it but with this new update it makes me want to change brands completely.
