Hi, it turned off autoplay for the next video, the video still plays but silent.
I also tried turning autoplay off on Facebook which works with Facebook videos but not videos on my phone.
This worked for me.... Go to the 3 bars in the top right hand corner in Facebook, select the dropdown for Settings & Privacy, then select Data Saver, tick the Data Saver box, & unclick the Always Turn off data saver when on WiFi.
This worked for me
While the videos are auto playing press anywhere on the screen and then the theee dots will appear in the top right corner. Press the ... before the next video plays or else it will disappear. Once you get the ... click on settings and then turn off auto play should be the first setting.
