I recently purchased a s6 pure and set it up to do scheduled cleanings at 6 am every day. The first 3 days went fine, but on the 4th day it started cleaning at 5 am. I resynched tge time zone. But then again today it started cleaning at 5 am.
Also, it is not possible to really see what time zone the roborock thinks it is in. All I can see in the app is "America/N...". It would be more helpful to see the entire time zone and/or UTC +/-
