I worked for a software development company for several years. We produced an enterprise level core business software program called Q360. I'm very familiar with the development process and the use of both web and desktop clients to access the data. I would like to suggest that you allow access to a single market like the USA from both mobile and desktop devices at the same time. I find it frustrating and limiting that when I access a market with my phone the desktop version logs me out. I would like to have both working at the same time. Thanks for considering this common approach that's taken by many other developers.
