Posting this here in hopes of saving time for eternal newbs like myself.
The repo link to grab the .deb file seems to be broken for myself and some others. Below is the steps I've used to successfully update (rebuild) Spotify.
Firstly if you haven't added the edit build option to yay menu; do so now:
In terminal enter
yay --editmenu --save
To pull and edit the build file:
yay spotify, then select
2 and it will ask you about
PKGBUILDS to edit use desired options for the first two and then
a to edit build file.
Change line 36 from
Save and exit build file.
y to proceed with install.
I did not have any user issues in Spotify after this. It launched directly to my user home as normal.
Suggestions welcomed from those more knowledgable.
