On mobile when we copy URL using YouTube App it is shortened URL, and it doesn’t work for “Grab from YouTube”.
We can off course get the full URL, by going to youtube using browser, but who does that on mobile?
Shortened URL contains youtubeId, but it doesn’ contain watch?v= phrase, and this causing the probem.
URL from YouTube App looks like this: https://youtu.be/youtubeId and we get this “invalid youtube url” message while uploading.
When we put watch?v= phrase in it, it looks like this: https://youtu.be/watch?v=youtubeId and it works like a charm.
So guys, if anyone have idea how to get this work, or any workaround for this problem, or in wich files look for solution, please write. I will be very grateful.
