Why are error messages so often unhelpful? Current example in itunes for Windows

The Apple advisor confirmed yesterday that I have the current version of itunes for Windows, which I had already removed and reinstalled from the Microsoft store. So I can communicate with the store. There is no VPN.

The advisor did conclude, or perhaps eventually find out from internal sources, that itunes for Windows no longer has an enabled subscription function, contradicting the error message to try again.

So it does look like the advisor is correct, and the error message incorrect about being able to try again and potentially have success the next time.

An Apple advisor told me yesterday that podcasts are now to be accessed on podcasts.apple.com. I also have an iphone with the Apple podcast app. I added several podcast subscriptions to my Apple account on the phone about two hours ago, all free. But none of them could be seen when I logged into my podcast.apple.com account.

Today's Apple advisor was very perplexed by this and asked me to wait on the phone for several minutes to check out what was going on. Why wouldn't new subscriptions added on the iphone Podcast app be automatically, and quickly, seen on podcasts.apple.com for the same account? My only option right now is to look at the list of new subscriptions on the phone app, key in each name one by one into the podcast web page search box, and create a subscription as each name is ready to play on the podcast app, so one by one and manually.

After a long delay, today's advisor came back on the phone and said in effect that no one on their end had it figured out, that there could be [not that there will be] an overnight sync of subscriptions between the iphone and the podcast.apple.com web page. But he was guessing, wishful thinking in my opinion.
