Microsoft last month released a new Insider build for To-Do users on Android with support for multiple accounts. This multi-account support is now available for all To-Do app users on Android. With this new multi-account support, users can add different Microsoft To-Do accounts and switch between them easily. This feature will be really useful for users who maintain Microsoft To-Do app for both their work and home life.
This update also fixes sign in loop for AAD users and offline logout bug for AAD accounts.
You can download the latest build (update 1.45) from Google Play Store here.
