Family tree mobile app: Bug report

Steps to duplicate:

Look at a person record's Recent Changes and select another patron ID to send a message.

Then browse back to Tree to add/copy a bit of Detail

Then try to go back /find that message you were in the middle of creating. The message has vanished. You will have to recreate the message if you really want to send it

Expected behavior: when creating a message it should autosave in the list of messages until actually Sent.
