I've been experiencing a bug where lock screen notifications begin to "disappear" (see video) when I get too many. I'm using an iPhone 6S Plus running iOS 10.2.1 beta 2, but I've had this problem since the initial iOS 10.0 betas. I submitted a bug report to Apple, but they haven't responded yet. Has anyone else experienced this bug? I haven't noticed anyone else complaining about it, but it seems weird that it's only affecting me.
