If the firmware update reset the configuration to defaults, you may need to reconfigure the button for the skip function. I tested the function here. It appears to be working with version 2157.I've noticed a bug with the skip function from the panel button. I tried the 2157 and 1909 builds, but the device seems to ignore skip commands. I can hold on TG and enter BT pairing just fine, but skip no longer seems to work. I have not tried from BTConfig yet.
