Google cast issues?
I've recently gone through a series of resets and cache cleaning on my android phone on order to trouble shoot an issue with Google cast, I.e. not working with Google speakers for more than one track. Clearing out the Google play services data finally appears to have corrected the issue for another app... But astiga seems unable to play to a speaker group. It can play to one individual speaker or pair, but no longer plays to a group.
I know Google had to jump through some hoops following the Sonos judgment, and I'm wondering if the cast API has changed and slightly broken astiga?
