I just bought a new "used" S9 that was factory wiped and everything. Got it all set up. The LED notification light does not work with my messaging app (Textra), and is spotty working with other apps (fb messenger). All notifications are turned on both in setting and in the app. Is there any solution to this yet? It's extremely annoying as I use the LED light all the time. Dissapointed that this could work just fine on an S7 and not a phone that's only what, 2 or 3 years old? I've been trying to search around for troubleshooting tips and sometimes stuff works for others and sometimes it doesn't. Wiped the cache partition and redownloaded the apps. Nada.
