Then don't buy a new phone ever year that comes with new OS
No serious. Hard to say why it is not working. Some gapps rely heavily
on Google play services. Maybe use logcat command to find what is wrong.
Anyway good luck with finding a work around if you persist using old app with new OS.
I don't see any more data traffic then old version. I manage the pages at news.google.com
to read exactly what I want to read. On top I have disabled background data for News and Weather App.
So it only refreshes when it is on foreground (mostly with Wifi connection then).
If you want this app only as weather app there are many more that give you sort of same data.
Cheers
