Will the limit for poll question character limit ever be increased? I like to ask polls in class but 256 characters is actually quite restricting.

Hi @Swerdna,

We are not planning to increase this at the moment but you could try adding poll descriptions to have more characters.

While creating your poll, simply select ‘Poll description' on the right-hand side and type in your additional text. This lets you add 256 more characters below the poll question.

Hope this helps :)
