Azure Portal home "Recent resources" shows resources from another tenant/directory

Hi,

I'm a consultant working with several customers, each with its own Microsoft Entra ID tenant (directory). My account has access to all of them and I switch between them using "Switch directory" in the Azure Portal.

Issue: in every directory I have access to, the Recent list in the Resources section of the Azure Portal home page also shows resources that do NOT belong to the currently selected directory, but to other tenants (other customers). In the attached screenshot, the two resources highlighted in red (an App Service and a SQL Server) belong to a different customer's tenant than the one currently selected.

If I click on one of these resources, the portal says I'm not authorized to view it, which is expected since it lives in another tenant. However, its name is still displayed in the current directory's home page.

This is a concern for us because:

• resource names belonging to one customer are visible while working in another customer's directory (e.g. during a screen share with that customer);
• in my understanding, the Recent list should be scoped to the currently selected directory.

Steps to reproduce:

1. Sign in to the Azure Portal and open some resources in directory B.
2. Switch to directory A (Settings > Directories + subscriptions > Switch).
3. Go to the portal home page > Resources > Recent.
4. Resources from directory B are listed; clicking them returns "not authorized".

The same happens in all directories I have access to, not just one.

Questions:

1. Is this the expected behavior of the Recent list, or is it a bug in the portal?
2. Is there a way to clear the recent resources list, or to limit it to the current directory?

Note: resource names in the screenshot have been redacted for privacy.

Thanks in advance.
