I just purchased Dsub yesterday, and it worked spectacularly that night, played great, everything.
This morning when I tried to add some files to the playlist via the app, I found that when I selected files in the library view, the buttons that usually pop up from the bottom did not come up. I tried going back and forth through menus and exiting the app via the exit command and going back into it, but I could not get the buttons to come back up.
I also noticed that while the bluetooth title streaming worked great last night, this morning none of the titles were being reported to my radio.
I'm including a screenshot, and the issue is currently happening, so if there is any more info needed, I can help grab that.
