@Crystal Liles Thanks for posting in our Q&A.
For this issue, it is not related to windows 365. Windows 365 is a cloud-based service that automatically creates a new type of Windows virtual machine (Cloud PCs) for your end users. This issue seems more related to Planner. I'm not a support engineer of Planner and know little about it. It is suggested to contact Planner support to get more help.
