Just created a poll ... Wish I had seen NutMeg's reply about the modify before ..
I was able to use as many options for voting, as I wanted.
Yet the photo only would allow one per post.
ALSO if it helps .. NEITHER Add more OR Clear attachment function worked.
I thought maybe glitch, and remove first attachment. It would not let me do that either.
So did post, for each additional picture to poll.
Maybe that can help Tech track down problem.
As both options, after adding photo. Not working at this time
