Doesn't work – Thumbnail Maker for YT Studio Review

I make the thumbnail, I save the picture into my library, on an iPod 5, IT COMES OUT AS A PICTURE THAT I CANT ADD A THUMBNAIL FOR A YOUTUBE VIDEO hey guys try out this bull crap. What am I supposed to do? Make people watch 7 seconds of the thumbnail by merging the picture with the thumbnail to watch the video? Screw this crap!!! also remove the watermark fix ur crappy app
