Send updates button not clickable

Hi, I send the first review for my app in marketplace.

After some time i receive some recommendations and notes about the changes I should addressed for the app to be approved.
I respond to all notes and make all the changes but now I can’t click on send updates button eventhough I have regenerated the authorization url as suggested.
What might be the issue causing this?

Hey @Medical_Learning

Thank you for bringing this up. Usually, an issue appears on the screen that you need to resolve. Could you please share a screenshot of the submission page to help us investigate the cause?

Thank you but I have tried attaching the screenshot but am getting an error that attaching media is not allowed. How can I attach a screenshot then?
