N minutes before or after sunset not working

I use the st app to control my lights.
I have a small automation that says 15 minutes after sunset turn on the lights outside.
This worked fine for years and stopped working two updates ago.
Now the light go on near sunset but about 30minutes early and the field to fill in the time say 15 minutes no longer allows me to fill in that field .

Same problem here. Minutes before/after sunset/sunrise are not working.

Sunset and sunrise times are static, they are not updating. Seems Samsung broke this during latest firmware release. History is also not listing my events, but they are being executed.

How do we get Samsung to log this as a real bug?
