It appears that the latest update (Sept 3rd) for the JBL Link Bar only introduced more unreliability.
Since the update I've had to reset it completely a couple of times to fix complete failures with the Google Assistant. It appears that after approx. 60 hours the Google Assistant will completely fail to respond to "okay Google" prompts. The Assistant button on the remote still works.
I'm beginning to think that this product is a complete lemon. After a year of delays they still seem to have released a completely unreliable product. It kind of does three separate things reasonably well (when they work at all), Assistant, Chromecast and Android TV, but as a whole it just doesn't work.
Great idea poorly executed. I'm resigning myself to the fact that Google/partners just don't know how to produce a reliable consumer grade product. I may just buy an Apple TV to plug into this thing!
The most shocking thing is that a normal test cycle for this thing would have identified all these flaws. I think they're aware of the issues and just decided to launch anyway. Awful.
I was really excited about this product, but I think I'll pass on this first version. Too many issues, I'm hoping Gen2 fixes most of them. If so, I'll be back.
