Well I can't say if it's a bug or not but it worked on my N9 but it does not work on Jolla.

If you start typing a text message to a person but then leave it and begin typing another text to a different person the written text would stay. Now with Jolla if you don't send the text off and switch to read or write someone else your all of your written text will be gone

N9 kept the typed in text even if you turned off or rebooted the phone.

Any news on when Jolla is opening together.jolla.com portal?
