Prototype Working half the time?

Hi there. I’m making an interactive prototype that I can send a link to people, have them open it on their mobiles, and have no troubles going through it. However, the prototype works only about half the time where frames will be black screens or the interactive components will suddenly stop working and leave the user stuck. It can be remedied by reloading the page, but then other frames and components will stop working (and having to constantly reload the page sucks).

I’ve heard that making the draft into a project may help but that hasn’t seemed to change anything.

Any and all feedback/answers would be great.

^Additional question/solution: Is there a different platform I can host the file on or a way I can present it as a shareable link externally?
