Is anyone familiar with how these fees differ from what they were charging previously?

This may just be publication of existing fees. I just checked a few buys from a few months ago, and the fees were the same as listed on this "new" link https://cash.app/help/us/en-us/3103-bitcoin-fees

Fwiw, when I tested Cash App vs Coinbase and Gemini fees in Jan 2022, Cash App had lower fees and much better spreads
