Final project won’t render/Export on iPad Pro (Low disk space error)

Whenever I try to render a large project, usually in the 1 gig to 3 gig range, I receive an error that I do not have enough disk space and the project will not render/export. When I check my disk space, I have 29-35gigs available which is plenty of space to accommodate the export. I've tried resetting the iPad, uninstalling and reinstalling Adobe Rush,  nothing seems to work.  The larger files tend to not upload either to where I can render on another device.  Has anyone found a way around this yet?
