Pressing "play loop" button does nothing


I am new to selenium and web automation etc. I am trying to play my macro in a loop but the loop button doesn’t do anything - do I need to add something specific to my code for it to actually work?

Added screenshot with blue circle around the “play loop” button.

Ok, my bad. It turned out that for some reason my browser UI is broken and the “play loop” “tooltip” that popped up was actually a menu selection.
