Feature description

When rebooting the device, displayed notifications are lost. This is unlike any other calendar app I've ever used.

Please add an option so notifications are kept across reboots. (And maybe make it the default)

Why do you want this feature?

I keep missing important calendar notifications or tasks I set up because after every reboot they disappear.

I use GrapheneOS and there are times where I receive multiple updates per week which requires a reboot so this issue occurs very frequently for me. Basically notifications disappear...

...when you reboot your phone deliberately
...when your phone crashes and reboots
...when there is an update and you have set up automatic reboots
...when the timer elapses which reboots your phone and puts it into before first unlock state.
