In order to improve the overall user experience of Planner by Tempo, we are phasing out the Team Timeline and making changes to the legacy Capacity Report in for Atlassian Cloud users of Planner.
For reference, here are images of the features in question.
Team Timeline
Capacity Report
The Team Timeline and the Capacity Report's team commitment and effective team size features will no longer be available or supported after March 1, 2023.
Replacing these features is a new and improved Team Planning feature.
Should you have any questions or want assistance navigating these changes, open a case with Tempo Support.
