I'm using a timer app, Multi Timer Free, but it doesn't show the time remaining on the lock screen. Meanwhile, Google's Clock app does. I want to set it to Show all notification content, but when I have Hide sensitive content turned on system-wide (which is always), Show all isn't available. Is there no way to make an exception to the rule?
I considered turning on Show all notification content system-wide, but then I'd have to select Hide sensitive content for a ton of other apps, which is a hassle.
This answer indicates that notification sensitivity is set by the dev, so I checked the Multi Timer Free settings (as well as the system notification settings) for anything that could designate the notifications as "public", but didn't see anything.
I'm using Android 9 on a Moto G6. If it's relevant, it's due for an upgrade to Android 10, I just haven't gotten around to re-locking the bootloader yet.
To be verbose, the particular notification class I'm looking at is Running Timer Notification.
