Smooth scrolling

Hi

While building my app, I observe that the only component that seems to provide a smooth scrolling on mobile are repeating list with scrolling set to ‘vertical scrolling’

By smooth I mean that scrolling up/down will elegantly make a travelling up/down the list while for other components it makes a instantaneous transition.

Would it be an expected behaviour, a config issue on my end or a bug ?

Many thanks

It is more obvious when you do it on the phone directly

Smooth is with scrolling with repeating group & vertical scroll

Not smooth is with group and repeating group & ext vertical scroll

I tried to replicate from scratch in the exact same configuration and it was working ok for all. So it could be linked to an external factor (project size ?, memory ?)

Thanks
