I also used Hide My Email to de-Google. I changed the email on basically every online service I use from my Gmail to a unique Hide My Email address for each service.

At one point, when I had fewer Hide My Email addresses, I was able to change my Forward To address. But now when I try to change it, it simply doesn't work.

I see the same screen as in your screenshot, but selecting a different Forward To address and submitting does nothing. There's no error message; the Forward To address just doesn't change.

I've been trying to update my Forward To address for months on multiple versions of macOS and iOS, and it doesn't work. I think the bug is related to how many Hide My Email addresses I have, since I was able to update it when I had fewer.

Another annoying thing, even if updating the Forward To address did work, is that you can only have one Forward To address for all your Hide My Email addresses. You can't choose separate Forward To addresses for different Hide My Email addresses.
