UX writing - recover message

Hello :D I'm recently working on my UX Writing skills.

Here I present you a small piece of work I'm doing, participating Daily UX Writing challenge. Below you can find the brief I based the design and copy on.

Let me know what you think!

Scenario: The user works in graphic design. While critiquing a design in a mobile app, their phone abruptly turns off. When they restart the phone, they reopen the app.

Challenge: Write a message that the user will read immediately upon opening the app. What do they need to know? What steps (if any) do they need to take to recover their content? What if they can't recover the content?
