I have seen some unexplained navigation behavior for a while now and just recently realized what is happening. I’m calling this Button Bleed.
Basically when I have a Form open over the Main display and tap the Cancel or Save buttons in a spot that aligns with a Button underneath on the Main display, not only is the Form button activated but the that Main display Button is activated as well.
The video below will demonstrate this behavior (my first time including a video so if you have any issues with it please let me know)
If the quality is not good, you can adjust the Quality settings using the Cog button in the lower right-hand corner.
