So it looks like the maximum number of redirects Apple Podcasts allows on episodes is 20, any higher and they fail to download or stream.
Just whipped up a test feed to find out: https://api.livewire.io/redirections.xml
For those of you about to add 21 analytics prefixes to your podcast, don't
Try out my test feed in other apps, and on other OSes and, if different, let me know what the limit is there
i.e. add the feed to your app, and try to download+stream the episode corresponding to the number of redirects
@js Another one of life's simple pleasures ruined by a meddling bureaucracy.
@js You found that by manually adding the feed to AP? I wonder if it would be any different if the feed was in Apple's catalog proxy because of iOS 14.5's changes.
@js that’s an improvement. It used to be 7.
