Hi, sorry for the delay! At this point the custom loading screen feature is not available. I'm checking to see whether it is planned to be added back.

Hi,
There shouldn't be a limit to the number of pages previewed, so it might be that there's a glitch with page 43. If you try loading one of the last pages on its own, does it work?

A note for future reference—you can find all of our recorded webinar videos in the "webinar" section of our YouTube channel: InteractBuilder - Webinars.
