Planner Tile Not Appearing for Some O365 licences
I had a user with E3 licence and Planner Service enabled . Though she could access planner directly via url https://tasks.office.com/
the tile did not show up at the office portal.
To fix this..
1. Set the planner licencing service option to OFF
2. Save the changes
3. Open the licencing service option again and set it to On
5. Ask the user to log off O365 and close all browser sessions.
In my case the changes were propagated within 15 min but it can take upto 24 hours depending upon the your tenant
