This same message started showing up on my BB earlier this month, and I have no idea why. Interesting that it's been an issue for years, and no one at BB or Google or whereever hasn't resolved it yet.
What's even weirder (to me, anyway) is the unclear impact of whatever the author of that message meant: what events are not being kept up to date: the ones on my BB going to my Google account, vv, or something else?
