A week or two ago I realised that - seemingly after a recent SD update - my Airspace Wanings settings were all reset to OFF, with the exception of Parachute Dropzones (which was defaulted to ON although I as far as I remember I had this set to OFF). This is the place in Navigation Options where you select the airspace categories you want SD to alert you of. I observed this simultaneously on two iPads (iPad mini 5 and iPad Pro 2020). AFIK, the user settings here are NOT synchronised across devices.
I found that the other warning settings (for obstacle and terrain) were not overridden.
Not sure if others had the same experience? You may want to check this to avoid busting somebody's busy airspace just because you didn't hear "Samantha" tell you about it ...
