I changed the snooze interval in Settings, but when I snooze from a notification it always comes back after the default interval instead of the one I set. Snoozing from the full-screen alarm seems to respect the setting, so it looks like only the notification path is affected.
You diagnosed it exactly — the snooze interval was only being applied on the alarm path, and the notification path always used the default. Version 1.15 honours your setting in both places. Thank you for the precise report.
