iOS App Bug: Sending email

Hello -
We have been experiencing issues with messages sent via the Mobile App. I know this is true for iOS, but cannot speak for the behavior on Android.

When clicking on “Send Message” there is no feedback or UI update to indicate that the message was sent or will be sent.
Instead, we have people who are spamming the button (sending dozens of emails) until they give up.

Expected behavior: UI updates to reflect the a message has been sent, no more messages sent.
Actual behovior: UI stays in the composer with send button. Hitting send button doesn’t do anything in the UI, but is sending messages for every tap.

Thanks in advance,
Itay.
