After the recent update the resume from last playback position is gone. Meaning, after watching part of a video and leaving, then starting it again it would start from where I left off (giving you an option to go back to the beginning if you want) Now, after the update all videos just start from the beginning.
Also, I would like use the favorites feature. I've read the support "Play the video you like and call up the control panel, click on the “heart” icon then the video is added to the “Favorite” list."
I have no heart icon on the control panel.
I'm using a Galaxy Note 9 with Samsung Gear
