Basically the issue is that for certain projects, Rush crashes or doesn't render. Usually this happens when I have several layers of overlays. I had to use the desktop to "flatten" the audio and video then I returned to my iOS (after learning that I no longer have full access to desktop with my $5 monthly; not looking to address that here) it finally rendered. Still can't figure why the video didn't originally render and crashes Rush. My first clip was an MP4 animation from Spark Post. But I've incorporated those before. There was some issue rendering the still photos with the video. Just a day of frustration. I made it work but I'd like to know why it's happening. Thanks for responding.
Also, not understanding why cloud sync didn't full sync to Rush on my phone. It seemed Rush was missing files that Inactiay originated on my phone. Just a day of weirds.
