Hello. I have searched the forum for solutions to this, but have found nothing that works to solve my issue.

Brief description of the issue:

My phone, an HTC One M7, running Android 5.0.2, cannot connect to spotify using mobile data (LTE, HSDPA, 3G, whatever). Connection via Wifi works alright. If I'm already logged in (via Facebook), it shows the message "no internet connection" in my native language (Polish) at the bottom of the screen. If I log out, I cannot log in if I'm using mobile data.

Steps to reproduce the issue:

Nothing to see here, it's simply that I cannot connect Spotify to the Internet and hence cannot play any music unless I'm on Wifi.

What steps you’ve tried already:

Tried the typical solution by uninstalling the app, clearing cache, deleting files (ok, didn't try this, as those folders listed here in the "spoiler" are nonexistent), reinstalling the app. Problem persists. Tried changing setting, checking APN, nothing. All other apps that use mobile data (e.g. Facebook) work perfect.
