Yeah, funny when it advises to talk to your IT admin, when you are the IT admin :)
Fortunately, obligatory unistall and install solved the issue.
Teams Q&A fails to start - error CAA2000B

We have an Office365 Apps for Enterprise license for our users and a Teams Essentials License for users who need to hold meetings.
We had been able to enable the Q&A feature, however, when trying to enable it now, it says something went wrong. If we click retry enough (5-15 times), we eventually get an error CAA2000B with a server message that suggests Yammer is disabled.
Error code: CAA2000B
Correlation ID: 1a90a2da...
TimeStamp: 2023-01-12...
More information: https://www.microsoft.com/wamerrors
Server message: AADSTS500014: The service principal for resource 'https://web.yammer.com/teamsmetting&#; is disabled. This indicate that a subscription within the tenant has lapsed, or that the administrator for this tenant has disabled the application, preventing tokens from being issued for it. Trace ID: 217b3... Correlation ID: 1a90a2da...
I don't think Apps for Enterprise or Teams Essentials comes with Yammer.... so is that the problem? I'm the admin and I definitely have NOT done anything to disable this in recent months.

Prerequisites for enabling Teams Q&A:
- Verify that you haven’t blocked access to Yammer’s IPs and URLs.
- To allow users in your organization to add Q&A to Teams meetings, you need to confirm that sign-ins for the Office 365 Yammer service are enabled in Azure Active Directory. Follow the steps below to confirm that sign-ins are enabled:
- Go to the Azure AD admin center > All services > Enterprise Applications > Office 365 Yammer > Properties.
- For the Enabled for users to sign-in? option, select Yes if necessary.
- Verify that you haven’t blocked the Q&A (Native) app in Teams app.
For more details about Teams Q&A, you could refer to this article.

2023-02-01T07:42:26.8+00:00 I'm not sure where I should go. I typically manage the settings through the "Microsoft 365 admin center". I've tried to deduce where to go in that - this is what I've done:
- Login to Microsoft 365 Admin Center
- Click "Show all"
- Click "Azure Active Directo..."
- A new tab opens calling itself "Microsoft Entra admin center" - NOT Azure AD admin center.
- I DO NOT see "All services", even after I click "Show more", however, I DO see "Applications"
- I click "Applications" and that expands to show "Enterprise applications" and "App registrations"
- I click "Enterprise applications" but there is no option for "Office 365 Yammer" and thus, I cannot pull up properties on that.
REMINDER: We have an Office365 Apps for Enterprise licenses - We DO NOT use any plan that includes Exchange (or Yammer.

Based on your screenshot, you only enabled Q&A through the meeting option. After my research, this error code is generally a team login issue. Please switch to Teams web client with a stable internet connection to see if the problem exists. Also, follow the best practices for setting up Q&A in this article to see if it works.
