Podcasts on iOS 14.6, serious loading issues

I've waited 24 hours to lodge a complaint, just in case the performance issues cleared up after the first day.

Many parts of the Podcasts app are loading very, very slowly. I have been testing the app in the same room as my router, so I am fairly certain that the bad performance is definitely the fault of the app itself and not a poor internet connection. I have force closed all other apps except Podcasts, and I've power cycled the phone.

When navigating to Library, I've found myself counting just to get a rough estimate of the load times. Just now after power cycling my phone, it took at least 12-13 seconds to display the Podcast Library page. This is not the only slow load time, either. Sometimes, I'll tap a downloaded episode that I had previously paused, and it can take somewhere between 15-30 seconds just to begin playing. The app provides no indication that audio is loading. Even when it plays, sometimes the UI doesn't update so I can't see how far into the podcast I am. After playing begins, sometimes it is unresponsive to other presses so I've also gotten stuck listening to the wrong podcast while waiting for the 'pause' to take effect, which again can take somewhere in the 10-30 second range. Even the page that loads the individual episodes for a particular podcast also has some significant load time in the vicinity of 5-10 seconds, which seems strange because I would assume a lot of these lists should be cached by now.
