Is there any way to get data back from pocket? I have been using it since it started to save articles for a book I'm working on. I have saved and sorted hundreds of articles. When mozilla acquired pocket I was so happy that it was taken over by a stable company. I had to take a year off from the project and I return to find this. I somehow missed the one email notifying me it was shutting down. My firefox search page to this day still gives me articles under a heading that reads "recommended by pocket" Is there any way to check if any of the info connected with my account still exists?

I was not able to download my pocket data before the deadline. So, I am desperately trying to understand if my data is absolutely, certifiably deleted or if I have a small chance of getting it back. Anyone can help me with an answer here?
