Thanks!

>I had a situation where my queen was being attacked by a bishop, and the board showed a "safe" space to move my queen, but that queen would have still been attacked by the bishop along that diagonal.

Are you sure? Can you send a screenshot? Any place the opposing bishop attacks would have a dot on it. (The green highlighting when you pick up a piece shows all legal moves, not just safe moves.)

The square to the bottom right of the Queen isn't "currently" visible to the bishop, but if the Queen moved into that square they'd still be killed by the bishop.
