I received a very nice and detailed response from support on this as my "subscriber permission" setting was not working as I thought was intended for LIVE youtube polls.
In Botisimo, the term "Subscribers" follows the naming scheme of platforms like Twitch, where you have "Followers" at the base level, and those who pay are considered "Subscribers".In the case of YouTube however, their terms are different. "Subscribers" are at the base level for following in YouTube, and "Sponsors" are those who pay to support the channel. So, in the case of Permissions in Botisimo, "Subscriber" = "Sponsor" for YouTube, and that's why your Subscribers weren't able to participate in the poll, because it was considered a "Sponsor" only poll.
So here we are.
I do think a "Follower/YouTube Subscriber" permission only option for polls would be very useful on Youtube and something no one else offers yet. For example, I do football content, and on Sunday mornings I get about 1k live viewers, my streams during the week are about 250. So being able to capture more subscribers when the hype is at it's peak (Sundays) would be very very beneficial to my growth.
Hope this is strongly considered for a future update and please keep me in the loop if at all possible.
