Black Screen When Previewing My Adalo App Need Help!

Hi everyone,

I have been working on an app in Adalo, and I recently ran into a problem. Whenever I try to preview my app, I just get a black screen.

It was working fine before, and I haven’t made any major changes, so Iam not sure what’s causing this.
I have checked my database and components, but everything seems fine.

Has anyone experienced this before? Any ideas on how to fix it? I would really appreciate your help thanks!
