Hey @eva thanks for your question!
You’ll need to be on a paid plan to have more than 3 video steps in a videoask.
Once you’re on a paid plan you can add in as many steps as you need, just keep in mind minutes are calculated by video and audio processing time.
You can definitely add multiple choice and buttons to the videos to allow people to choose different options and skip on to the next video step.
If you’re planning on upgrading, next week we’re running a promotion, you’ll get 25% off the Grow or Brand plans so might be worth waiting till then to upgrade!
Let me know if you have any other questions 
Many thanks Grace!! I’m so happy that this is possible! Yes, I would like to use your yearly Brand plan.
Unfortunately I still have to get client’s agreement, so I’m not sure when this is going to happen but of course I will rush to get this promotion. 
I will back to you once this is happening. Have a nice weekend!
Awesome! Have a great weekend too @eva
