Hi @L. HEWISON,
Thank you for posting your question in the Microsoft Q&A forum.
You’re definitely not the only one running into this, several users have reported issues with Assignments not loading in Microsoft Teams today, and I have been seeing similar discussions come in across the forum. I’m actively tracking the situation as well. You can also take a look at another thread I responded to here, where users are reporting the same behavior: Teams assignments not loading - Microsoft Q&A
At this moment, Microsoft hasn’t yet listed the issue on the Service Health dashboard. To help accelerate the investigation and push this to the product team sooner, I’m encouraging affected users to notify their organization’s IT admin so the admin can formally report the issue through the admin support channel.
The more reports Microsoft receives from different tenants, the faster this can reach the appropriate engineering team for a fix, so every bit of input really helps.
If the information here helps clarify the current situation, please consider clicking “Accept Answer.” When an answer is accepted, the thread is automatically pinned and highlighted. This makes it much easier for other affected users to find the information quickly and contributes to gathering community signals in a more focused way.
I’ll continue to keep an eye on the situation and will update this thread as soon as any new information becomes available.
Thank you again for taking the time to report this.
