Project Accelerator de Microsoft

I am running some tests with the Project Accelerator tool. I assigned a Planner Plan 1 trial license based on the documentation and previous guidance. At the beginning of February 2026 everything was working correctly, and I was able to view tasks inside the Project Accelerator application.

However, as of today (February 25, 2026), the task view no longer loads, and I receive a Microsoft authentication error. It seems as if the system is now blocking access to the plan view even though the Planner Plan 1 license is still active.

My question is: Have the licensing requirements changed recently?
