The pic on the left is my brother’s phone, the right is mine. I have gotten countless prompts to update the FB Messenger app, which I have done. I do not have the app lock feature that can be seen on the left. I’ve done a bit of research and it seems that the update has rolled out to everyone with the app at this point. I’ve tried every troubleshooting trick I can come up with. Does anyone have any advice to offer? This is driving me crazy. Thanks tons.
