How do I get my podcast submitted. I keep clicking the submit podcast to apple from simplecast platform and it takes me to podcast connect, but doesn't give me the option to connectg

I don't know anything about siplecase, but what you need to do is to have the URL of the feed ready.

Then, sign into iTunes and establish a payment method there (if you haven't already done so). Authorise the computer to play itunes purchases.

Then go to hhttps://podcastsconnect.apple.com

Sign in if ncessary. Click the \+' sign at top left. Enter your feed URL in the field provided and click 'Validate' at top right. If it passes validation you will see a 'Submit' button.
