A collaborative workspace app in Microsoft 365 designed to help teams co-create, stay organized, and work together in real time across apps and devices.
Hi G_6084,
Greetings. Thank you for posting the thread to our community.
I understand your concern, it seems the Loop component of your Class notebook in Teams is not working properly. For the situation you’ve encountered, I do understand the inconvenience caused and feel very sorry about it.
After my research, the Loop component in OneNote feature was rolled out and generally available to all eligible users on the current channel with a commercial M365 subscription since Sept 6th, 2024. For your reference: Uplevel collaborative notetaking with Loop components in OneNote - Microsoft Community Hub.
Since you mention the issue suddenly happened and I’m afraid and sorry to say I didn’t find related service incident. Due to this situation, I’m afraid this is a temporarily server-side issue needs to be investigated from back end to find the cause. The support team has higher permission to remotely assist you and collect background logs for the root cause. This is a more efficient way in handling this case for you.
If you are an admin, I recommend you get support by following steps from this link: Get support - Microsoft 365 admin | Microsoft Learn.
If you are not an admin, you can contact your admin to contact Microsoft support. You can look for the way to find your admin through this link: How do I find my Microsoft 365 admin? - Microsoft Support
Please accept my apologies for redirecting you to the related team support, as the moderators in this community have limited resources to verify the backend information and to get the quick and better assistance, we requested for this.
Appreciate for your patience and understanding.
Hope you having a nice day.
