I've tried the Touch Feedback (sound / vibration / vibration and sound options) today.
Mobile app v2025.5.0
device: Samsung Galaxy A52, Android 14, touch feedback is enabled (sound, vibration)
When adding new points, the sound does not play sometimes - it happens seemingly random, say, after setting the option "sound", first 5 points were without sound, then some with sound, etc.
I did not manage to get the vibration, regardless of the settings.
