Button press inconsistent on ipad duet now?

was thinking that my button presses were not coming through consistently but i see now that it’s meant more to press quickly and move on. Is there a way to modify the button, or another widget to use, that is more for pressing and holding? So for VJ world to turn on a white strobe while i’m holding one down and then add other colors over the top by pressing other buttons for shorter intervals below … happy to make a video if it helps

using a tethered ipad via duet app

It should work for pressing and holding. Are you saying the behavior changed? If you use the mouse instead of via duet I assume it works as expected, right?
