Hi, A friend has recently bought an arc one powerbase, they have added two apps, but both of them do not seem to work. The first kept telling them no bluetooth connection, even though the powerpack was green, and the 2nd wouldn't give any tracks under the "arc one" selection./media/tinymce_upload/417957f7878a9f98d55b5f79b83c9dc5.jpg Can someone tell me if I have downloaded the correct app? Or is there something else that I am doing? Or where can I do to get a solution? Thank you to anyone who reads this and many thanks to anyone who takes the time to help. Kind regards, Silvio
