Hi Guys,
I think that this issue is already reported on github. Unfortunately i haven't seen any progress there.
I've got exactly the same issue with my OPO and Orange in Poland.
What i noticed that from time to time i'm able to send and receive MMS. To do it i had to disable and re-enable APN settings few times, change to Flight mode and change back to the normal. Unfortunately after OS restart problem is back.
Is there any possibility to view log files of this messenger app or enable debug mode to check what's going on?
Small update,
I just installed Logviewer app and reporduced the error. Below you can check what I've found in application-legacy-messaging-app.log

I don't know why this date and time is mentioned there 2018-02-18T08:37:27. The date is Ok but correct time is 09:37:27 so +1 hour.
