Spotify Login Error (8) on new device

So I’ve been using Djay for years, first started out on the iPhone 4, then upgraded to iPhone 6 with no problems at all. But ass soon as I upgraded to the iPhone 7 and downloaded djay, I received the spotify login error (8) while on LTE. I tried signing out of all devices on the spotify website, got new password for device, uninstalling and re-installing, and noting has worked. Even though the app works fine on wi-fi, it’s still annoying when out on the road. I’m under the t-mobile network and internet connection is always great. Playlist load fine even though I get the stupid error, songs just won’t load into the deck while on LTE, but works fine when I immediately switch back to wi-fi. Please help somebody.

Thanks bro but I tried that
