Hi
Sorry for a (very) late reply.
After one of the recent Spotify updates, the connect App started to work again. However, there seems to be a stochastic effect somewhere in the loop, as the availability of the connect functionality shifts on a daily basis. I have made tests with two different WiFi routers, but the experience seems to be the same. Luckily, I'm in a good stream and at the moment I have access to Spotify Connect 🙂
