Internal browser works when VPN is up, but no other apps work (like Chrome, Firefox, JuiceSSH, etc.). Samsung Galaxy, Android 10, on WIFI & cell data. It only works if you disable manual DNS settings on your phone. I had mine running through 184.108.40.206, didn't work. Set the phone to automatical DNS and then Pulse works fine with external apps.
It used to be fine running manual DNS. Please check into this.
