A few reactions: Although you can just turn off notifications at the app level, this is annoying because it means you can't won't get notifications for emergency/safety notices, people messaging you directly, etc. The number of relevant agencies will vary by your location, and in my 10 years on ND I have only received an agency notification once or twice. However, I think agencies were only introduced a few years ago…
iOS only lets you turn off bluetooth for a day at a time.
The problem is that Apple is too stupid to respect the setting you make there. If you turn off Bluetooth in your system settings, they should treat the control panel's Bluetooth switch as a true on/off. But no; it's always temporary.
Sometimes Apple can't figure out how to solve simple UI problems. When they even bother to try, their "solution" is an overly complicated, unreliable mess.
