As I said, If I enable it, that blocks me the possibility to use the entry button in the keyboard because it’s replaced with the emoji button. I am not sure if it’s just a problem with the keyboard but AOSP keyboard which is always without maintenance and it would be great solve it from Delta Chat side and I found an option.
By default, with emoji button in entry box by default, I could use the entry button and pushing it a moment I can use emojis from keyboard.
Some screenshots,
Option disabled:
Option enabled:
Note: In both cases I am pressing both entry and emoji button on the keyboard to show the possibility.
