it used to be 2022/02/07 and it was easier to manage in excel. Now the defualt format is changed to Mon Feb 28 00:00:00 UTC 2022 and is hard to change.
@Asuka97 how are your dates setup in lookml?
Same problem in my instance: dates are set up via a time dimension group in lookml based on a timestamp field from BigQuery.
Confirming that I have the same issue with formatting. Same setup as kbinder53.
I also got the same issue starting from last Monday. 😞
