By the language you used it sounds like you’re involved with the project, so thank you!
If it helps at all I’ve been experiencing this issue for probably 6 months or more. I’ve just gotten into the habit of adding videos to playlists and closing the video after i know it has been paused for a while. If I open it again from the playlist it picks back up where I was.
Also oddly enough if it skips to the end and I let it go to the next video (not in playlist, but whatever it would have played next) then I hit “back” it will (usually? I haven’t tried too many times) pick up where it should have been from when I paused it.
Edit: actually nevermind “we’ve been given fixes” would imply you’re one of us plebs! Thanks for the info anyway lol
