I exported a project which I thought was completed, then upon uploading it found that I had made a mistake in editing and figured I could go back into rush and fix it then re export. I had forgotten that I had to delete the project in order to free up space because the app told me I didn't hav enough space to export, even though I had plenty of free spaceon my phone, almost 60 gb of free space to export. I'm sure the project is gone but I hope some how there is a way to retrieve it. Thanks.
Unfortunately, if you remove a project and it is not synced to another device through Creative Cloud, that project is probably unrecoverable. You can delete the app without deleting projects, but deleting projects is pretty permanent.
