Hi @kristina_athena welcome to the community 😊
And great question, we still have an open feature request for this. I think the response is that having the button is necessary for the form to know when you’ve finished selecting your options - but it’s a great point that on mobile it’s covering text. Do you by chance have a screenshot of this experience that we could see? I’m upvoting the feature request so any additional info helps! 
I see there are some suggestions for having more customization around the button so maybe that’s the answer, but will keep you posted on any updates! 
                
     
                                    
            Hi!
 
I don’t have a pic… but I feel like they should be able to submit their question once they select the multiple choice or hit enter on what they’ve written, no?
