In case you cannot see the pink compose-new-message dot at the bottom right corner of Inky, please try either of the following workaround:
1. Quit and then restart Inky,
2. Reboot your Inky device by turning it OFF and back ON.
For Android, Quit/Restart and then "Force-Stop" the app.
For iOS, Quit/Restart and then "kill the app by doing the swipe up after double clicking the home button".
