Issue with Apple Podcasts Cover Art

Hey, I have an issue uploading my Apple Podcast from Spotify RSS feed. When I check the feed, I can see that Squarespace is automatically appending a format parameter that sets the max width of the image to 1500px (see the attached image for reference). 

Apple Podcasts need a 3000x3000 px resolution so the cover art isn't loading. Is there any way to fix this? Thank you!
