Form does not show in PowerApps Portal

[nguhoa]

I have an PowerApps Portal with some forms a month ago. Everything works fine.

Today when I created new PowerApps Portal and try to use the existing Form (updated to new Portal) and a fresh new form to insert data to the entity.

But both forms do not show at all in the Portal (only see blank page).

If I setup this form for "Create new record" in the entity list, I an see this form when try to create record for entity list.

Is there something wrong with PowerApps Portal's Form recently? or is there anything that I can try to make this work?

Thanks Oliver!

After update the Basic Form for 2rd web page content, the issue is resolved.

Appreciate your quick help here.
