I'm in NZ and mine changed permanently as well the day before yesterday. There are a few errors that I need to change though, ie some place names , like London Ontario instead London England, and a few other things, which are proving elusive to fix, but I'll get there. No choice really.
I would much rather have the old Site - the overview page was brilliant and concise, THE WHOLE THING WAS ACTUALLY, and simple for a new user or a guest to navigate. I like to make my own stories, not read some machine's interpretation of my family. And I will be happy when Ancestry stop sending me hints from my own trees! LOL - But that's not new!
I wouldn't be signing any online petition, they are a wonderful source of info and email for scammers and frauds!
I don't like it at all, but like everything, things develop and change and we just gotta go with the flow! I'm sure they will keep tweaking it for a while yet, and some things will change again just when we're getting used to them. Oh well, my Bank just changed their website as well, so hard to navigate now, but there you go, it's the way of the world!
The older we get, the harder these changes become, and as much as I don't like them - we can't stop progress - we just have to jog along for a while until we're running again with the rest of the 21st century! Pity . I liked the 20th! 😏
