Trying to get the currently logged in user's groups. Trying to get at that by using the user ID. I am currently testing as Admin - user number 1.
Craft::$app->getUser()->id
Returns a user ID (11) that does not exist in the Users table. The Users table has ID's of 1, 20, 21.
How do I get user ID or more specifically, the currently logged in user's groups?
