Pencil Tool - Not Drawing Curve Arrow?

[Affinity iPad Student]

I followed instructions (I hope) from @DM1 and @Alfred  from a post I made awhile back. This one:

 

 

I don’t know what I am doing wrong. Arrow is not appearing once I draw.

As in the post I linked, I tried to replicate @DM1 

I chose pencil tool, I chose rope option, whatever I am doing wrong - I don’t see it. Can someone guide me please, thanks:

Hi Affinity iPad student,

Please could you make sure you have arrow heads set in the stroke panel as shown in my attached video.

Thanks
