Double-tap should show you the menu until you make an initial selection. Then, it should show you a short message to indicate what is happening on a double-tap.
Thank you. After more experimentation this morning, my 10" Lenovo tablet (Android 5.0.1) it is working correctly, although it crashed several times (unable to replicate crashing).
My LG LM-X420MM (Android 9) is also working, although no confirmation message appears (maybe screen real estate issue?)
Thanks for implementing these much needed features.
Edit: I have updated status on all other of my control devices:
Samsung Grand Prime SM-G530T1 (Android 5.1.1): All works including confirmation
LGK20 Plus (Android 7.0): All works including confirmation
Asus P00A 7" tablet (Android 7.0): All works including confirmation
So, only my newest LG phone has no confirmation. THANK YOU
