Verizon Messages (Message+) not sending media

[lrub]

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.

lrub, I rely on text to communicate, so I know how important a resolution is to keep you connected. We are here to assist. How is cellular data working for other apps and the web? Do standard text messages go through?
