Good app but a few bugs are present

This is a really good news app but it has a few bugs it needs to fix. Top bug is now every time I open it there is a warning that my receipt cant be authenticated. Dont know what it means and have tried multiple uninstalled and reinstalls.

Meanwhile it claims to sort topics by region such as a section for Canada. I find more non-Canadian news content in there than actual Canadian content.

Also would it kill them to include a feature that allows an exclusion of certain news story types. Example: could care less about sports and have removed the sports topic tile. But I still get sports flooding my newsfeed.
