Samsung Smarthub Youtube app has gone

[lat002]

I'd been having trouble getting my Samsung BluRay's SmartHub Youtube app to run so yesterday (11/05/2015), changed the DNS setting to Manual and entered 8.8.8.8 (as recommended elsewhere on Tom's Hardware forum) and it started working well.

I tried to run the app again today but the Smarthub deleted the Youtube app. It is no longer in the apps 'library'.
I reset the DNS to Auto and did a Smarthub reset but the Youtube app is still missing. Has anyone got any ideas?

Update: On 13/05/2015 I reset the DNS setting to Manual and re-entered the address 8.8.8.8. Afterwards, I started up the SmartHub and it did a 'Service Update' and loaded a new version of the Youtube app which works great.
It therefore appears that Samsung and Google are continuing to support the Youtube app on my Home Theatre I'm pleased to say!
