My Question or Issue

How to keep the Spotify notification permanently in the notification screen? Because my homescreen widget requires this to work properly.  I whitelisted it on my phone power saving mode but same problem. Thanks

Btw i already posted this in Reddit and it seems that many people are having the same issue https://www.reddit.com/r/GalaxyNote8/comments/azhoec/can_we_keep_the_spotify_notification_permanentl...
