Recently we have encountered this problem with some new clients: 'Unauthorized access to cart'

- They have portal access

- Are logged in on their personal account

- Account is not shared, but accessed by a single person

One thing that comes to mind is that each had access with a demo account, prior to us creating a personal account for them. Could it be that the demo account is still active in another tab / window causing this problem?

One of the clients has responded and says they have logged out of the demo acccount, yet the problem persists.
