I guess it was tested on a computer and video was taken. I’m running this test from my phone. The device I use is using it with samsung galaxy s7 edge and chrome browser. I have completely cleared all browser history in its advanced mode and when I tried it again on the demo site and my own site, I ran into the same problem. My request from you is that you have performed this test on a mobile device and if you do not scroll back to back, swipe down a little and wait for a little while, swipe up a little and wait for a while, and if you test it on the mobile device, I am sure that you will encounter the same problem. Because I encountered this problem on the demo site, although I tried it for the first time with a few devices my family owned.
