The phone is an S9+.
MMS media will not send through Message+.
Images hang forever on "sending", and videos immediately fail.
There is no way to cancel and retry sending images, and when I try to resend videos I get the error message: "Can not resend this failed video message" (poor grammar and all).
I can send media just fine using other messaging apps. The problem occurs both on and off wifi.
I've tried restarting, and have verified everything is up to date.
