I constantly get that problem. Doing a MS Learn and create a resource in a Concierge Subscription. I can go to the resource. I can see the resource on the home screen in recent. If I go on All Resources with no filter, the resource is not there. If I go back to the resource from the recent, and click on the resource group of the resource, the resource group do not list the resource.... If a click refreshes a dozen time a display to show "simplified view" show up and magically a view that list all the resource show. If I go back to the other view, it disappears again and no possibility to get that "simplified view" again...
Eventually, after 20-30 minutes the resource will finally show correctly everywhere...
I experience this for months, and it seems that problem existed for years... its impressive how many little bugs like this MS keep unfixed in all their lineup of product these days....
