‘Invalid file” on each attempt
I have 18 AVI files to convert to MP4. Of the reviews in the App Store this one seemed the least shady. I downloaded it and paid for the upgrade immediately to avoid any potential frustrations as early as possible. The app opened, and was intuitive, but every AVI file I tried from my files app would pop up the conversion in process window, might get to 2%, then give me a window with “invalid file” and stop the process. This does not work as advertised
