Yes, I noticed the reversal in the past week or so here on Ancestry.ca. Very annoying.
The other date issue for me is that the UK Death Registration sources have the dates in US format (mm/dd/yyyy) instead of UK (dd/mm/yyyy). So any day 12th or less is switched to the month. I have begun to just assume it's switched and put the UK date in my tree. I reported this to Ancestry in March 2024 but so far nothing has changed (not holding my breath).

I have never had a date from UK Death Registration in anything other than normal UK format (dd/mm/yyyy).
Hi. Took me a while to find one. It's actually the UK Death Index, not Registration. The person's birthdate is 6 May, and date of death is 1 Dec. On one record, both dates are in the incorrect format, but on the other they are both correct. (Additional sources were found that confirmed the correct dates.)
