I am able to send and receive SMS and receive MMS but I cannot send MMS in Facebook messenger when I am connected to Wi-Fi. I have tried tampering with many settings like Wi-Fi calling and mobile data always on and various other things but nothing seems to be working.
I am running a Samsung Galaxy S8 with Android 9 on Verizon.
I have scoured many online forums and it seems this issue is pretty widespread, but not universal, with third party apps on Android.
Is there a way I can fix this?
