Since a week, maybe because of last update, I cannot like videos or follow people. When I like or follow, the action is reverted. When I go back to the video it is not liked, and when go to the person profile, s/he is not followed. What's going on? I did, as recommended in the help, cleared cache, restarted the app and phone, updated, tried in wifi and data. I even erased all app local data and logged back in. I waited days of use, and still nothing. Can't find a solution online. Can you help?
