Sam-I-am is correct. This was a false negative message. This has been resolved in 8.10.0 update.

It seems like everyone is getting this message.
I've seen many users ask about it in the lobby.

I too got the same message, but I didn't notice any change at all, so just ignore it. It almost has no effect.
