This currently causes a split-brain scenario for the application due to the priority of each level. Granular settings assumes a simple override, however the crypto setting wants per room to be overriden with the global setting, regardless of the room setting. Some additional comments are needed on the intended behaviour. Signed-off-by: Travis Ralston <travpc@gmail.com>
