Lock Screen Apps and LED Light both not working (GS6, Nougat 7.0)

[AC Question]

Ever since I put my phone in and out of ultra power saving mode a couple weeks back, it has not been displaying lock screen apps, nor has it been showing LED light notifications (for text alerts, charging, or charged).

Things I have done: taken the phone in and out of medium and ultra power saving mode. Restarted the phone several times. Selected different lock screen apps and made sure they were enabled.

I have no idea what's going on here, but I would like my phone to be functional again while locked, since that is how it spends most of its time...

Update: I fixed the LED light by turning it on in "Display." Not sure why Nougat moved the LED notification option out of the "notifications" settings, but there you have it.

The Lock Screen Apps remain non-functional.
