Several people have reported netflix loading to a grey screen on the most current version for the nook tablet. They've also been told that Netflix says it is a problem with B&N.
I'm sure B&N will say it is a problem with Netflix.
They need to get their developers on the line with each other to work out the bugs.
A soft reset does not work, nor does a hard reset to resolve the issue.
Please look into getting netflix working on the nook tablets again.
