When I installed WP 8.1 preview my phone was working great. With this recent update given, I installed it with no problem, until today. My computer recognizes my Lumia 920, but will not connect Full Speed 2.0. Is there anything I need to do on my end to remedy this? Has anyone else gone through this issue. I hate having to leave my phone plugged in for over an hour just to add a few songs and re-syncing.
