HI @nitsanc If I understand correctly you are trying to hide arrows by WF GUI option hide at each end
What this option does is hide arrow ONLY on one side if there is no other slide after or before (mean on first and last slide).
To hide arrows on mobile is simple task, go to mobile viewport, select arrow an set its state as hidden after apply identical approach on second arrow and you are done. This will hide arrows only on mobile viewport.
