I have two lights, both FGD212's, that now flash-on and then immediately off again when no off command has been sent. I have other FGD212's working OK though.
On one FGD211, this will start a sync and receive a neighbour list, but fail quite quickly with a timeout error every time. Again, I have other FGD211's working OK though.
Neither of the above problems I noticed prior to the upgrade.
