Have been using Video Joiner for over 4 years now, it's one of my favorite video editing apps. Still on iOS 14.7.1 with an Apple iPhone X. (256GB storage space.)
But just recently, been having some issues with the app: Namely, I can't import a video (to extract ONLY the audio) when I click on the "audio" button. Even with a 3-second clip, it takes forever to load and then when the video is imported, Video Joiner crashes on me.
I've tried re-booting my iPhone to start fresh, but the same scenario happens. I even tried deleting some projects I don't need anymore to free up some RAM.
My last option is to delete the app and re-install, but I don't want to do that, as I'll lose all my projects.
