I'm using facebook Messenger on a Samsung Galaxy S9. Since a few months now, Messenger keeps on playing a notification sound when receiving chat messages even when I change the sound to Silent.
Let's be precise :
- When going in Messenger parameters and choosing a notification sound, there is no "silent" sound (and I'm pretty sure it existed before)
- When going into "Manage notification" from the app which leads to the notification management of the OS, I can chose "silent" as a sound but after a while (1/2 hours or so, sometimes less), messenger changes it back automatically to its default sound.
That's driving me crazy. I want to keep notification as I used to : vibration, preview but no sound.
I tried to delete and reinstall the app, nothing has changed. I even left a message in the Play store.
Any idea ? Thanks
