Thanks for this fix which solved the issue for me. I inherited the app with the iOS 9 update (UK) and having set up my "Topics", off which there were many, from the excellent choice, the App worked really well. I was/am really impressed and would rate it as possibly the best feature for my personal needs.
Ufortunately it stopped working on my iPad in that it just went to a non responsive white screen and froze for a while before crashing out. Strangely the problem did not manifest on my iPhone (maybe that was to come!).
I applied your fix on the iPad but note that there was a message saying:
What would you like to do with the previously synced iCloud News data on your iPad?
Keep on My iPad
Delete from My iPad
Cancel
in my ignorance I chose the delete option but on opening the News App I was greeted by the new use set up screen with all my chosen topics seemingly deleted. Without panicking (!!) I closed the the App down and repeated the process but chose the "Keep" option. On opening up the App my chosen topics were/are there. I do note that the iCloud setting seems to switch itself back on. The App however is still working but at least if the problem recurs, thanks to your help, I can now easily reset the App.
Again many thanks BUT a SOFTWARE FIX NEEDED FROM APPLE IN THE NEXT IOS UPDATE Please.
Regards
