How to recover my data after updating my app to the newer version

I updated my Kobo Collect app to the latest version (v2023.2.4) but my work isn’t displayed on the interface. It’s on the device memory as HMTL files but it’s not showing in the app interface. How can I really display it there and I work on it and finalize the project?

Welcome to the community, @Anoldkass! Maybe you could do it as outlined in this post discussed previously:

Are the HTML files that contain your work compatible with the updated version of the Kobo Collect app?
