Try letting go of ctrl after the first a, so the sequence is ctrl-a, a, d. Man screen:

C-a C-a (other) Toggle to the window displayed previously. Note that this binding defaults to the command character typed twice, unless overridden. For instance, if you use the option "-e]x", this command becomes "]]".

C-a a (meta) Send the command character (C-a) to window. See escape com‐ mand.

Or if you're using tmux instead of screen for Byobu, try just ctrl-a d. Byobu's default prefix key is ctrl-b, so if you're using that default, doubling up the ctrl-a keystroke would not be necessary.
