some times Spotify dose not start.
I found the problem a few weeks ago online, when that happens you need to delete SingletonSocket, SingletonLock and SingletonCookie in $HOME/.var/app/com.spotify.Client/cache/spotify/
I did this the last few weeks manually at least 1 time peer week, more like every second day.
But it happens to often for my liking, so i made a small script:
Wow! thank you very much! Had this problem yesterday with Discord and needed do kill and start it like 5 times to get it running. Today i had it with spotify and decided to google it. Worked perfectly on first try and it started in like 1 second!
I will try to make a shortcut which first deletes the files and than starts spotify.
And i will search for a similar fix for discord!
