To create polls in BuddyBoss App, one must tap/click outside of the input boxes to proceed to the next step.
However, on mobile the keyboard covers most of the mobile screen and there is very little space to tap/click. Also, clicking outside an input box is not intuitive user behavior on mobile.

Tech support answered my question so I can now create polls, but I doubt any of my users who try to create polls will be able to find this solution on their own. So my suggestion is to fix the poll creation so it does not require tapping/clicking outside the input boxes for BuddyBoss App.
