Frequently asked questions:

• Can I subscribe to a feed from my device?
  The only place to subscribe and unsubcribe to feeds is in Google Reader 
• I have a lot of posts to read, the ‘river of news’ presentation is not really working for me
  Since version 1.2 we will be provided a more ‘conventional’ interface besides the river of news interface where you first see a list of subscribed feeds, you then tap a feed and then you see the posts in that feed.
• I installed Doppler but it does not allow me to select feeds after I enter my username and password?
  Due to a bug in Doppler 1.0 you might want to check if you have non-alpha characters in your password. If so, please change your password to only use alphanumeric (a-z, A-Z, 0-9) characters. This is fixed in version 1.1 
• I want to share a post, but it tells me an error occurred and that I should try again in a while.
  We found an issue in Doppler 1.0 which causes this for certain posts. Doppler 1.1 fixes this.
