Dormant App?

I have projects that have not been used for some time due to covid. When I try to open the app on my phone, it is empty and says “not found.” When I am logged into the Glide site, I can see data, and the google sheet with the data exists. Did something time out? How do I fix this?

When free apps are dormant for a long time, they will automatically unpublish. You may just need to publish the app again.
