Huawei — honor band 3

On monday, 23rd october, i bought an honor band 3 from amazon. The functionality was decent and every feature was working in a satisfactory manner. Yesterday, after updating to firmware 1.5.15 from 1.35, sleep tracking no longer works properly. Despite repeated complaints by users in the google play store in the huawei health app and huawei wear app, the developers still haven't made any changes whatsoever and sleep tracking continues to be useless.
It is astonishing to see such levels of complacency from a company like this.
This was a terrible experience. Simply releasing products in the market without having the resources and technical expertise to back it up is meaningless.
