Android 9, Samsung Galaxy S+, Spotify Premium, U.S.A.

I see this is an ongoing issue marked "NOT RIGHT NOW."

I keep getting the "No Internet Connection" message on your Android app, but usually only when I'm on wireless. This has been ongoing. To solve it, I have to switch over to mobile data AND restart my phone. Spotify works on wireless for a while after that, but not after the phone goes untouched for a few minutes.

I've tried:
* Signing in and signing out
* Uninstalling, restarting, and reinstalling

Spotify on my other devices (Chromebook, Windows 10) works all of the time, no problem. I have no other issues with apps and wireless on my Samsung.
