Pro tip: A lot of websites that don't let you update certain fields about your profile or other things actually do let you, because it's a full payload patch on the backend. You just need to modify the fields in dev tools.

Note: I did this on a hotel website to change my email address and then ended up creating a bad scenario where my login account email didn't match my hotel profile email...they fixed it for me and said, "we aren't sure what happened". I didn't say anything.
