Cover & Episode Artwork not displaying properly in Apple Podcasts on iOS17

I’ve noticed two issues:

#1: With the latest Apple iOS 17 update, my podcast artwork is not filling the full space compared to other shows.

#2 My episode artwork also doesn’t seem to be showing properly even though it validates fine: https://www.castfeedvalidator.com/validate.php?url=https://josephliu.co/podcast/feed/podcast/

Any ideas how to fix these? Thanks!
