I also noticed the other day that the S21 display? no longer works in tinySA-saver, but screen capture still works fine.? I had intended to test further, but my life has been so scrambled lately, I think I'm going to start? reporting anything like that immediately and not wait until I have time to explore the issue further.? If I remember correctly, I did get a straight line at zero, as if all the? data it received was zero with no variation.
