I've tried, and no matter what, piglins won't give me a gold ring. I tested this in a creative world, and it didn't work. Also, on my world I have a mod that adds more advancements to the game (It's blazeandcave's advancements pack) which ended up giving me an advancement for getting all possible piglin trades. However, I didn't get a ring. If there is a way to craft this or something like that, please let me know. Thank you!

Yeah, same problem here, also it says there should be option to enable or disable golden rings in the config file but it must be missing cus I cannot find any mention about golden rings in the config file

In creative, I used stack and stacks of gold blocks worth of gold to trade and nothing.....
