Hi @Karen2428
I'm so sorry to hear you're having problems with the messaging on your app. Are you able to give me a little more detail so that I can check this out with the tech team?
Can you confirm what mobile device and operating system you're using (e.g. iPhone X, iOS 13.5.1)? If you could confirm if you're trying to do this via wifi or using mobile data too, that would be really helpful.
It could be worth trying to log in on a desktop computer if you have one, and sending the message this way.
I'm sure we can get to the bottom of this for you 🙂
