Facing issue in Apple Podcasts Connect
I signed up and logged into my Apple Podcasts Connect account then it ask me to activate my Apple ID. How can I do that?
This has been a problem for many people: indeed almost every post from people who are creating podcasts is about this rather than issue with their own podcast. As it's internal to Apple I can only offer the following standard advice, which may or may not help; probably it won't but there really isn't anything else I can suggest.
It's become apparent that you cannot log into Podcasts Connect with a Developer ID - see below. You must have a payment method registered in Apple Music/iTunes: make sure your computer is authorised to play purchases (Apple Music or iTunes menu Account>Authorisations>Authorise this Computer). Then try logging in at https://podcastsconnect.apple.com
For help with the process of creating a podcasting account please see Create Apple Podcasts Connect account - Apple Podcasts for Creators
If this fails I would suggest reporting it Podcasts Support: https://podcastsconnect.apple.com/contact-us , though if you haven't been able to complete the submission you may not be able to access them: in which case the next step is to contact Apple Support: Support
Don't present this as a podcasting problem - they don't handle those and will refer you to Podcasts Support. Present the problem as being the inability to access Podcasts Support. It's also been suggested that getting them to look at your Apple ID may clear matters.

As to Developer IDs, Brian Ogilvie has discovered the hard way that you cannot use a Developer ID to sign into Podcasts Connect, and details the steps needed to create a new ID in this useful post.
