RobOK We were really looking forward to the "Meeting Notes" Wiki service being replaced by a version using the OneNote service. But that's not the route Microsoft took. Instead, they decided on the Loop service (I'm still scratching my head over that one).
If you disable Loop, you will lose the built-in "Meeting Notes" feature. You will just see the ole' fashioned meeting details when you open the event...there will be no loop component at the bottom. Since our users never liked the previous "Meetings Note" feature, they have just been centralizing their meeting notes within their personal or team OneNote notebooks. They also utilize the Notes tab of their Teams channels. So, in our case, they are just continuing to use the process they have been using. However, maybe the upcoming Loop integration with OneNote will make it so users can still centralize those meeting notes...and then we can re-enable Loop. I guess we will have to see.
Here is the info for disabling Loop:
