I don’t think it’s a network issue as I can use Spotify on other devices.
Ipad 1 is using same iOS as last few years also there hasn’t been upgrades to older Spotify app. They must have changed something on the server side. I can’t see from iPad what is Spotify’s server response.
Same problem here. Version 0.7.2.26 last supported version on ipad 1st gen. Already tried two separate wifi connections. Hard reboots. App reinstall. I have multiple older ios devices (all gifted cause I can't afford them) at home and they all stopped working at the same time. Streaming music from playlists works. Problem is encoutered in the "What's New", search, inbox, radio, and friends tabs and it kicked the app offline until hard restarting the app. So it's definitely a server change that affected the browser portions of the app. The app didn't change.
I'm actually amazed the app has continued working for this long as the usual tendency is for companies to care little about updates breaking unsupported devices after a couple years. It's not that they can't. Developers are amazing people who can code almost anything. I work with several and they are always eager to solve challenging problems. It would be amazing if Spotify is different from other companies and unofficially supports older device users. Don't plan on it though. Financial decisions often tie the devs hands. Maybe we'll get a kind dev who has some free time to figure out a patch to keep us working for a little while longer. If not at least itunes still works. :)
