YouTube app keeps pausing the video

I am using a Nexus 5 D820 rooted stock Android 6.0.1 MOB30D. The YouTube app version is 11.x and is the latest as I checked for the updates today. The app pauses the video at random. I had to tap the play symbol at the center to start it to play. This is not same as buffering as in buffering one would see a progress and the play symbol does not come up when the video is stopped. - I tried this with my headsets and without headsets to rule out the press of headset button or something allied to cause the issue. - I also tried this in 3G and in WiFi, both in high res and low res. - I also tried this in offline mode. In each and every case, the YouTube app pauses the video almost for once for every minute. I do not want to switch over to another app and I cannot uninstall it as well. Does anybody have any solutions? Thanks.
