OK that seems to have fixed the issue. the messages are going through, however there are two issues that need attention.
- On pressing the Send Message Button the spinner on the button does not stop, even though the message is delivered.
- The attachments - in the last message I tried, I attached an image and a PDF and the recipient did not see the attachments. I have attached a video showing it.
At the time of writting the spinner has been spinning for more than 15 minutes now, even though the message has been delivered and read by the recipient.
