It doesn't matter what type of VPN. It's the GUI that's broken from the tray, NOT the actual connecting of the VPN. Connect from the VPN panel in settings and it's perfect, but from the tray, it'll occasionally work, but will usually hang on "Connecting". Cancel it and connect the same VPN from the Settings panel and instantly connects.
And while 1909 works a bit better, it still will exhibit the same behavior occasionally, especially after a reboot.
