Hello @Vivian6,
Lovely to meet you.
Just a thought, can you try clicking into your 'Profile' found on the bar on the bottom righthand-side of your app. Then click 'Settings' > 'Notifications'. If you scroll down, to 'Text Message Notifications' you will see a just below this 'Messages', this should be selected (with the button pressed to the right).
I've found when your app updates, you usually get a pop-up notification asking if you would be happy to switch to push notifications, but it is sometime easy to not soak in what this means (if you are like me), so this might help. 🙂
Let me know how you get on.
Thanks,
Lizzie
