We decided last week to give Google 1 more week to get a fix out for their version 5 OS. Since that doesn't seem to have happened yet, we've started the process of trying to find & fix this on our side.
We'll keep you posted on this thread about what we find.
For those having this issue, will you please post your Build Number that's shown on your About Tablet form? For example, I just upgraded our Nexus 10 to 5.0, with Build number LRX21P.
Thanks for your patience,
Walter
