Would you please check if you have filled out all the mandatory fields? Are you getting any error messages?
In order to assist you further, please share a screenshot of the application page beyond which you cannot proceed.
We are happy to know your application went through. Usually, the district notifies the applicants by email or message if their application was accepted within a week or two. You can also check the application status from your district application page.
If you do not hear back from them, I would recommend you reach out to the district directly to know the status of your application.
