@John ******
they'll give you a few chances to fix any issues. They won't just deny the visa if you don't submit everything they need.
Beware though that once you submit through evisa, you're done with that system. Any future requests for new documents will be done through email, you can't upload new items through evisa after you submit.
So keep an eye on your status in evisa and if it changes to something like "request additional documents" check your email and spam filter.
