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 :)

Just curious - why are questions capped at 300 characters?

Hi ​@Hi Tech,

The main reason is to keep questions short & sweet, while still providing enough space for the audience to share their thoughts fully. We’ve set a 300-character limit for audience questions to help keep questions clear, concise and easy for moderators and presenters to manage during meetings and other live events. Longer questions can take more time to read and answer, which might slow down the flow of the Q&A. 

Hope this helps 

All the best
