Green has Native Segwit 🕵️‍♂️ https://help.blockstream.com/hc/en-us/articles/4406838277401-How-do-I-create-a-Native-SegWit-account-

Hm, I must've missed the option to select native segwit... Idk how I overlooked that. Thanks for the reference!

OK, I just set up a new account on Android, and can confirm legacy vs native segwit was not an option, when setting up a Liquid wallet. Maybe its a Liquid thing?
