I followed plenty of guides about this and got my youtube API Key.
I keep trying to insert it in the configs but when I hit save, the key disappear from the field and when I try to add a youtube link to a product it keep saying:
Error: "Video cant be shown due to the following reason: Youtube API key is invalid"
I went to the api settings, restricted the key for YouTube Data API v3.
Anything else I should do?
Edit: The key disappearing was due to folders not having rights anymore... Still the api key show's as invalid when I try to have a video url.
