I had issues with Hola on my Android, which got resolved after an upgrade of Hola itself. After that it got broken somehow again, where Netflix is unable to see a network connection. That then got resolved again by rebooting the device.
On my main desktop I've not seen any issues.
So I think this is an isolated issue where certain things broke as opposed to Netflix being responsible.
One of the things that make me quite convinced of that is that I still get the nice 'You're watching Netflix from a different country, keep these things in mind' popup from Netflix, with the mentions of different series/etc being available for you, and your favourite series might be missing.
