Hi, I am facing this issue on my Facebook Messenger app for the past few days.

For the 1st incoming message, the notification sound is the default 'ding' sound.

For subsequent messages, the notification sound is 'Tri-tone'.

How is it possible that one app can 2 different notification sound? Unable to find any solution. Anyone facing the same issue?

ios 14.7.1

Thanks
