Blank form

I need help, in the app when I click on filling out a new form it is blank. I can open the form on the computer but it doesn’t appear in the app.
Where is the error?
I downloaded kobocollect on an android phone. I opened the application and clicked on enter the project details manually, entered the URL https://kc.kobotoolbox.org, and also entered username and password.
Even with all the kobo functions correct.
