I gave it a sincere try, but the UX is so utterly subpar that it's simply not worth the time or effort anymore. The file management on iOS is atrocious: support by various editing apps is questionable at best, and even if it wasn't, it's incredibly slow. Waiting while importing high-res videos off SD media to the file system, then turning around to wait an equally long time for the media to get imported into your editor is extremely irritating. There's also not a lot of serious competition in terms of quality editing apps. It seems like everything other than Luma Fusion is gimped to the point of near-uselessness for anything but the most basic of cut-and-crop type workflows.
iPad did have a slight edge in terms of render performance and efficiency versus ultraportable notebooks like the MacBook Air for a brief period between the A12x-based Pro release in 2018 and the release of the M1 MacBook Air in 2020, but now that the M1 Air is on the table, it's well worth the few extra ounces to go with a M1 MBA for mobile video editing.
