EVERY episode of a podcast I just listened to yesterday is now “temporarily unavailable”, frustrating is an understatement.

I have seen this question many times, but have yet to see an answer that fixes this. This happens all the time to all kinds of podcasts of mine no rhyme or reason when it just happens randomly. I was listening to one of my podcast yesterday, all day long, many episodes from a while back. Now today they are all temporarily unavailable. Why does this happen? Why can’t it get fixed? I don’t get it. Please help! Or if u can’t help, but know why this happens, I would love to know that too!
