We have multiple users verifying invoices. When user goes to the inbox section of Medius and Incoming Invoice inbox is visible the first invoice on the list is automatically selected. This causes invoices to be blocked and not accessible for other users. Alternatively allow filtering (and saving that filter) the Incoming Inbox by sender's email. In our case sender is always the person who will verify the invoice and many times they find their document being blocked by someone else, just because that person just signed in to Medius.
