A cloud-based task management app from Microsoft that helps users organize and manage daily tasks across devices.
I also have the issue! It hasn't been addressed yet -- for months now!
Nothing listed here works. And btw when I try to open Settings > Apps > Installed apps > Microsoft To Do > Advanced options -- the moment I click on the "Advanced options", the Settings window ALWAYS crashes without even showing the error code or something like this.
Of course it is possible to open ms-settings:taskbar and open Taskbar Behaviors and uncheck+check "Show badges on taskbar apps". But doing so dozens of times per day -- is pure madness.
The app itself must be profoundly fixed and properly QA-ed by Microsoft, and fixed version must be released.
MS development team, please fix the app ASAP!
