As well as the free Weather App for Samsung from the Galaxy Store, I also have the registered Google Play Store version both being version 10.28. The Google Play Store version has a timeline/progress scale bar on it so you can see what time the rain etc is due to sweep in overhead. Alas the Samsung version from around the same time and with a version no also starting with 10.28, fails to show a timeline and just has past and future buttons. Please fix this Samsung so we can all get the benifit of your expertise!
