Hi, does anyone else having problems accessing HN with Dolphin Beta on Android?

About 50% of the time I try to open HN it just loads forever. Then I exit the app and reopen and then it works. Also sometimes when I hit "back" to go back to HN I get a certificate error dialogue, but it still loads after that. I don't have any problems with chrome on the same phone&network.

I'm in the UK on GiffGaff and I'm using a nexus5 with stock KitKat.
