Cannot access Planner app on Android device

1. Uninstall Planner

2. Uninstall Company Portal (your phone might require you to uncheck or remove it first as a Device Admin App before it can uninstall it).

3. Install Planner and try to login, it will ask you to install Company portal, go ahead and install Company portal again and set it up.

4. Go back to Planner and login again, it should then go through its checks and complete login (you might have to do it twice).

5. Open Outlook and set it up again as removing Company Portal should have removed your work profile from it.
