Scripted Dropdowns not working on Acrobat app

I've created a fillable form with a few of the dropdowns running off a custom keystroke script. See attached. The dropdowns in question are under the power and strength categories. The scripts work in Acrobat on my computer but don't work when the PDF is opening in the app on an iPad or iPhone. Any suggestions for why? I've attached the PDF as well as a video of what's happening in the app.
