I have been using Enpass for a long time. I have one account and one vault stored in the cloud. Recently, I switched laptops and I installed Enpass on my new laptop. But when I want to connect to my existing vault, I get the error the no two vaults can be connected to the same account for syncing data. But I only have one vault and I am trying to connect to it from a new client? This was always working fine. What is going wrong here?
