I've had my Galaxy Watch 7 for a week and the weather complication never updates unless I manually refresh the weather in the weather app on my watch. I never had this issue on my Galaxy Watch 6 so this must be a new bug with One UI 6.
If it helps I have location permission set to always on for both the weather app on my watch and my wearable app on my phone. I have automatic refreshing set to every hour. I'm using this watch with a Google Pixel 8 so I wonder if this bug is only with non Galaxy phones as it doesn't seem widely reported.
Yes, I believe the issue only impacts those who don't use Samsung phones as my friend with the same watch and a Galaxy S23 Ultra doesn't have this issue. It looks like if you have a Galaxy phone it just updates the weather directly from your phone but with a non-Samsung phone you have to set the manual refresh times in the watch app itself however they don't work.
It's strange because I used my Galaxy Watch 4 and 6 with a Pixel and never had this be an issue.
