Chromecast Update Bringing Grief For Many Users

An anonymous reader writes: Last week, many Chromecast users were automatically "upgraded" to build 32904. Among the issues seen with this update are placing some users on the 'beta' release track, issues with popular apps such as Plex, HBO GO, (more embarassingly) YouTube, and others. Google so far has been slow to respond or even acknowledge the issues brought by customers, save for the beta release mishap. If you're a Chromecast user, what's been your experience?
