Hi @Fergart20 ---- Thank you for the report and sharing this observation you have made with us. The insight is very appreciated!
Moving forward, just to make sure we are on the same page here 
You took the update to B339 and when Roon came back online you were logged out and have not been allowed to login again. Is this correct?
Furthermore, can you please provide a description of your current setup using this link as a guide so I have a better idea as to what gear you are currently working. Please be sure to verify what you have running on the Roon core as well (i.e “Roon”, "RoonServer, “Roon”+“RoonRemote”).
Lastly, since noticing this behavior have you tried downloading the latest version of the application directly from our website?
