Smart Hub deletes apps on TV restart

[KiwiTim]

I started having trouble with resetting the country on my F6700 TV?s Smart hub recently. When I reset to UK, the UK apps initially load, although not the Samsung App Store app. When I restart the TV they get deleted. Same deal if I set the Smart Hub to Australia. Tried a full factory hard reset, but still UK and Australia get deleted after Smart Hub country change and restart of TV. Some countries do remain (I won?t say which ones in case our Samsung friends are watching), but only a few. Most seem to get deleted. My Model is UA50F6700AMXRD, purchased in New Zealand. I use UnoTelly DNS unblocker service.

Obviously I can?t ask Samsung for help with this issue, but am wondering if you have come across this issue before. Thanks in advance!
