提案/Suggestion
Prevent the Return key from sending the message under “Contact Support”. It should do what it says and insert a carriage return and new line. There is already a yellow arrow well-placed, away from the text entry box, and this should be the only mechanism by which the message should be sent. All that having “Return as Send” does is to create a load of half-formed messages, just because the sender is trying to create a new paragraph in order to make the message more legible.
現状/Current Status
Under “Contact Support”, the “Return” key sends the message that is currently being written. It should instead just create a carriage return and new line. There is already the yellow arrow to “Send”.
