Chat sometimes doesn't display messages

Sometimes, the chat doesn't display the messages I typed. I need to re-start the game for them to show up.

Edit: I know this description is quite vague, but there is not much more I could add.

Yes, I have this problem too. (iOS)

When I leave the app, and enter again, it still doesn’t show up. But if I close the app by tapping home button twice (close it from running in the background), the mesaage now appears when I enter the game.

I'm playing on Windows, so just shutting down and opening the game again does the trick. Still a bit annoying, the first time I thought it was a mistake on my side and spammed the chat with the same message over and over again.
