After uploading video using youtube api with oauth2 authentication(as Desktop app) and code from https://developers.google.com/youtube/v3/guides/uploading_a_video which is modified to compatible with python3 changing print function and httplib to http.client, YouTube locked uploaded video as private so no option to change as unlisted or public.
Same video file with same title and same description uploaded via youtube studio in webpage isn't locked and other user can watch it.
Sentence 'For videos that have been locked as private due to upload via an unverified API service, you will not be able to appeal.' from https://support.google.com/youtube/answer/7300965?hl=en is suspicious, but I can't exactly understand what that senetence means. Actually, there is appeal button on locked private mark.
I really hope someone can help me... thanks!
