[Watch series 7] Precipitation complication not working

I have added a "rain" or "precipitation" complication to my apple watch face.

But the issue is, it remains blank most of the time and only sometimes, a percentage is shown.

Rest of the weather data, like, temperature and conditions are displayed properly but issue is only with precipitation/rain complication.

As much as I remember, when I got the watch, this never happened.

It started happening after an update (few updates back) and even after updating to the latest watch os too,

I have the same issue.

I have reset my watch, set it up as a new watch, reset all settings on my iphone too, but no avail.

My iphone too is in the latest iOS version.

In the attached picture, the umbrella icon usually displays a number (0% to 100%)

But it becomes blank for some hours again.

I couldn't find anyone else facing similar issues or mostly getting resolved after enabling background app refresh and allowing location access. I tried both, but didn't help.

Any help is appreciated!
