Sorry I don’t know the answer but maybe you could just export to Photos and then import that into YouTube using the website.
Yes you will lose your projects if you uninstall LumaFusion but there should be a backup in the Files app. I’d play safe and duplicate the whole LumaFusion folder in Files before deleting.
Thanks, Mark, for the help!
I’m aware that there are other ways to upload to YT.
I was just wondering how to fix this obvious & strange problem/bug.
Too bad that there’s no way of resetting some settings, like the currently logged-in YT account. The fact that I don’t get the YT/Google login dialog lets me assume that I am already logged in. But then the account‘s name is missing in the GUI. Don’t know how this could happen.
On my iPad Pro in the LumaFusion folder there’s a „Projects“ folder with 3 items and a „Project-Backup“ folder with 22 items – in LumaFusion, however, I see 8 projects. Have to find out now how to really backup all current 8 projects with all their media files ...
