I've tried to export a project multiple times, but nothing seems to appear anywhere on my device. It even gives me a green notification saying it was saved to Gallery (which I don't really have - should be to Photos or Camera or something, right?).
Premiere Rush v. 220.127.116.117
72 GB of memory available
Exported using automatic setting as well as 720p/30fps. Finished video is 1 min long, clips used were created on my Pixel.
