Default notification sound instead of SMS sound (v0.15.16)
The latest update on f-droid changed the notification sound when receiving a SMS: it is now using the default android notification sound, instead of the one configured for SMS (the sound configured in Silence settings is the same as the one in android system settings).
Downgrading to 0.15.15 fixed the issue.
I have not tested google play versions.
Last working version: 0.15.15
Not working: 0.15.16, 0.16.11, 0.16.12
