Lewis,

The changes you made seemed to do the trick as I'm now able to sign in using Google+. Thank you so much for the communications and ultimate resolution to my issue.

Same error message is given.

I've been told multiple times now that this issue has been 'fixed', but I just tried again today and the same error message appears. It's very frustrating to receive these types of communications only to find that the issue still exists.

I hadn't seen an update reflecting the new build mentioned above so I uninstalled Quell Momento and reinstalled it from the Google Play store. The application information shows that I have version 1.09. I'm still not able to login using Google+. I receive the following error message: 'Unknown issue with Google Play services.' I've tried the suggestions above with no luck.

I'm able to login using Google+ in Quell and every other application using it as an authentication mechanism. This error only happens in Quell Momento.

If it matters, I have the application installed on a Nexus 7 running Android 4.4.2.

Here's hoping that this issue *really* gets resolved. I'd like to be able to take advantage of the additional perks that come from being signed in.
