While trying to edit long video on my iPad Pro 11, the preview window often freezes and and nothing renders no matter how long I wait. My only fix for this at the moment is to use the readjustment slider which forces a rerender of the preview window. I've seen on the Adobe Rush support page that rendering may fail at times due to low battery. I've tried this at low battery, 100% battery, and 100% battery while plugged in and nothing fixes it. I've tried deleting the project and redownloading it, no fix. I've also tried reinstalling the app, still not a fix.
EDIT: I’ve discovered the issue only occurs when the device is in landscape mode.
Sorry for your issue!
Thanks for trying all those troubleshooting steps and finding out that landscape mode could be causing it. Which version of Rush are you using exactly?
