I feel like in general online services, meaning services that you do on chrome or any web browser, have a specific capacity/ storage. On the Episode Writer’s Portal this can be seen when coding. Whenever, you add too many overlays or characters the reviewer freezes. (I upgraded my computer with a 32GB ram FIY) In my case, I just added 60 overlays and no characters. I was excited to view my coding and then the previewer just freezed and skipped to the next scene. same happens on phone app previewer unfortunately I know it’s too much for chrome/ portal so I think a coding program/ application only for episode would solve this issue.
