Text message app suddenly unable to send image attachments

[PacificaBren]

I'm using a Samsung Galaxy S9, model number SM-G965U, running Android version 10. It is not rooted.

The text messaging app I use is simply called "Messages," and it's the default messaging app Samsung and/or T-Mobile included with this phone.

My problem is that when I try to text a pic to somebody, it just sits there with a little ball spinning around to signify the process is, well, still processing. Then, eventually, I get a message telling me the item failed to send. Text messages themselves are able to go through just fine; it's only the image files that are a problem.

I have tried:

Restarting the phone
Connecting to my home WiFi instead of the T-Mobile network
Forcing the app to stop and clearing its cache

What else can I try?

Thank you.

Did this just start happening or is an ongoing issue? Is it every picture or a particular one (file may be huge maybe)? Can you tell if it's Google Messages (does it have RCS) or Samsung's?
You can try a different SMS app just to see what happens - Textra is great.
