Team members don't see their tasks in EPM and the EPM manager in Resource Center

Hello,

the project plan is published.

The "Publish" column contains "Yes".

The tasks contain few Resource Names.

The Resources are defined at the higher tasks. I.e. Task

• 1.1. "Project Management" contains the resources and the planned work. Start and end results from 1.1.1
• 1.1.1 "Status Management" contains no resources and no planned work

But, the team members don't see their tasks in EPM Resource Center --> Resource Assignments. But, the EPM manager sees, that there are planned task in Resource Center --> Resource Availability.

Before a few days, the team members saw their tasks. Can someone tell us, what's going on?

Thanks and kind regards
