Excel Linked Data Types missing when using multiple Microsoft 365 accounts

It took me quite a while to narrow this down, but if you have multiple Microsoft 365 accounts and one of them don't qualify for Linked Data Types then the feature will be missing until you logout of the limited account.

I posted this example to the broader Microsoft Community, but it really belongs here.

Hopefully this will help someone else who stumbles on this behavior.
