Online Meetings GET calls do not contain all data anymore

Question

We have been using the graph API /onlineMeetings get calls to retrieve the meeting data successfully for the past few months. Unfortunately, since about two days, we now get incomplete information anymore.

For example, the call to:

GET https://graph.microsoft.com/beta/users/{user_id}/onlineMeetings/{meeting_id}

used to return a meeting object filled with the subject, end time and other information. Now it is very sparsely populated, i.e.:

This issue persists across both the v1.0 and the beta interface. The meetings have been ended, and the data should be there. Have there been some changes we should be aware of?
