YouTube video upload issue

Hey, when I try to import a longer YouTube video which should be split into more parts, only one part of it appears in my library. I can’t figure out where’s the problem and how to acces/upload the second part. A few weeks back I didn’t come across such issue.
Thank you for your help!

Can you check again now and let me know if additional parts appeared? If not, please send a link to one of videos you weren’t able to import properly and let me know what browser/extension you used.

(Sorry, this is the account I’m actually active on. Made a mistake signing in.)

Here‘s the link anyway. I’ve used the share function on iPhone and iPad and also tried to import it manually (copying and pasting the URL) in the app.

Thanks. Do you have an issue with that one specific video only or with other longer videos too?
