Hi @Bolyard, Alan,
Thank you for reaching out to the Q&A Forum.
Regarding your concern about the missing chat grouping feature, based on your description, it appears this issue is related to an ongoing incident currently affecting the Microsoft Teams user interface.
You can find more details about this incident in your organization's Admin Center under the Service Health tab, listed as Issue ID: TM1139221.
In the meantime, a temporary workaround is to clear the cache in the Teams desktop client, which may help restore functionality.
Additionally, we recommend reporting this issue directly to the Teams product team by navigating to: Settings > Feedback > Report a problem
Your company’s Global Admins can also report the issue in the Microsoft 365 Admin Center via Service Health, as shown in the screenshot below.
