I recently purchased s8+ and after few hours of user pinch to zoom started working on youtube.
However, recently after 22nd feb youtube update youtube zoom has stopped working.
I tried force closing youtube, clearing data for the app but it didn't work.
I tried clearing the device cache in recovery mode but that didn't help either.
I tried downgrading the youtube version by removing the system app and installing an older version. That didn't help either.
I also enabled the video enhancer and changing the performance mode to entertainment. But, all in vein.
Surprisingly same version of youtube app is installed on my lg g6 and that works flawless. So, my hunch is this is to do something with our device.
Have you encountered this issue? Or, if you have resolved it using some method? If yes, please comment.
