NRFPT Only displays in landscape mode, and the controls aren't working. I can't start/stop the clock, or change between 12 and 24 hour display. The ✅ beside "Chime" comes and goes. but I don't know if that actually turns the chime on and off. This is a Galaxy Note9 running Android 10 and OneUI 2.5. Once complete, I'm hopimg this app will allow turning off elements like the surrounding box, the time in 12:34 format, and the explanatory bit strings below the time. This is a very good start.
