Robrix has great shortcut functions including the "Send Message with Keyboard Shortcut" that can be toggled on/off. As it is a "global setting" it should be shown but maybe be grayed out or be under a "desktop specific" heading for mobile devices?
The mobile keyboard (at least on iOS) always has a dedicated send button (the paper plane) and CTRL+ Enter is not an option for mobile keyboards as they don't have the CTRL button (or Function buttons).
