I think you can, never tried it to see if it breaks anything after a while
nostr:npub1am3ermkr250dywukzqnaug64cred3x5jht6f3kdhfp3h0rgtjlpqecxrv7 have question - can this notification be completely avoided by switching it off (the 'Service' notification) in settings and let Amber work on background?

Or is it necessary to keep Amber somehow in working state. The list is still rolled out and it taking a lot of space in notification area.
Have unrestricted and run on background allowed for battery.

Tested with notification off. Untill Amber is back from background, no action is usually confirmed. Amber is quite often missing from the list of 'Active apps'.
Don't know why, so many remain there all the time. So far not working good with this setting.
Can the relay connected notification info list be configurable, by default, to display as a single row only, matching the screenshot above?
In some future update.
The 'roll it up' doesn't remain in effect and list often reappear back in full length.
