I'm running ver 4.52.2 on my Android. I tap "Card Reader" from the Settings menu and then the only choice is to "Learn More" about one of the 3 types of reader.
@msollins Hmm...this sounds kind of odd. When there is no option to connect a reader, it usually means the hardware or software on the device is not compatible with the reader.
Have you checked to make sure your device is compatible with your reader?
