iTunes won't download podcasts
I'm running iTunes 12.10.11.2 on a Windows 7 desktop. It's recently started refusing to download episodes of certain podcasts, throwing up a grey exclamation mark symbol (which I can't ever hover over to get information from, because a play button covers it as soon as the mouse goes over it).
Initially, this was only happening for one new podcast I'd subscribed to, then newer episodes of ones I've already been listening to (episodes from late 2022 ish) and now spreading to many podcasts, regardless of age of episodes. I tried deleting and readding one podcast that had been affected and it now won't even download/acknowledge episodes that I've previously downloaded and that are clearly still on my harddrive.
