It's always been slow, but the "Show this event on LifeStory" addition seems to have reduced things to a crawl.
The failure to replicate marriage changes to the spouse is definitely a new bug. They will no doubt claim it is intentional. After all, they claim to know more about the event concerned than any person can, so don't see the point of having any explanation, descriptive text or transcription. Some of their event types don't even have a text field.
The failure of LifeStory geography is anything but new. Ancestry just can't parse postal addresses. I am pedantic about having country mentioned in my addresses, so they have no excuse for relocating things to the other side of the Atlantic. After all, we have three countries on the UK mainland.
Even addresses within the USA are affected. They can't figure out where the White House is. Try "1600, Pennsylvania Avenue, Washington, District of Columbia, United States of America" and see where Ancestry claim the President lives. When I complained, they suggested that the cure was for me to remove street addresses and just have towns and cities.
Added: I've just found out that you can now have the bride and groom marrying each other on different days and in different places!
