This app is worse than the previous one and with less work being done to fix it. Been a user since 2007 but the bugs, crashes, and unworking functions have made it more of an annoyance to use than anything. If you like to open an app and gamble on whether you're going to have a functional user experience or be irritated with the inconsistent working "functions", or be completely moved out of the app and lose your place, then this is definitely your app.

The app is full of users that intentionally derail conversations and troll the community. Multiple issues with the apps functionality. The main issue being the edit feature and posting pictures, which is so difficult, most users have no clue how or if they can do it. The edit feature turns something simple into an exercise in patience as the app tends to mash words together. Something as basic as changing one letter becomes a hassle.

Meh yeah it seems to work. But there's some bugs that are really annoying. Once you watch a video sometimes you can't scroll and have to close and reopen the app. If you swipe too fast the app goes back. And it doesn't seem like the developers even attempts to fix any of these problems
