I have changed my rating from 5 to 2 because of numerous reasons. 1. Auto play function of videos on NewsFeed are now off; 2. I'm sick of updating Facebook every two days and as new updates are releasing, the app is getting sicker to use. 3. I use Vivo V15 Pro and I also have a strong WiFi network, still page loads too slow and sometimes I automatically get logged out. And 4. The developers are sick. They don't even respond to their users' problems. Kindly change your development team Mark
