On my browser I click the upload button and then it opens this app. This app doesn't have a upload option. If I wasn't use to beyond stupid things like this, this app would not have been possible to even keep downloaded on my phone because it opens automatically. I only give it 2 stars because I know a work around by opening the upload link in chrome, in a new tab, then declining the YouTube studio ad it shows. That, or the upload option in the app is not obvious to know it's to upload.
