It's not recommended to login to multiple projects at the same time. 

A browser is connecting to the Dapresy server to login and show you the information you need. Once you open a browser, a session in that specific browser will be generated and certain details are stored in a session to make requests to the Dapresy server faster. However, if you login within a browser to multiple projects, the browser doesn’t understand which project you are in and it might mix up information in the request to our server. 

As a workaround, you can browse via an incognito window to a second project or via another browser type.
