I used Google Ai Studio to help build an app for my business and I published it just for use within my business. Over the last couple of months things have worked great but as of sometime between the night of June 30th and the morning of July 1st I have lost my database of patient files within the app. All that is left is a few dummy files that were created when I was making the app before publishing. It is like it reverted back to the start. The app itself is fine but all my data is gone. I have not received any errors on my end. How can I get this data back?
