The update has broken a bunch of things for me..
On my desktop using firefox, I cannot get images to display & everything is slow to load. On my android phone, boost was showing me a ton of stuff that I do not follow & wasn't showing me any info about my profile (profile tab would not load or something). Boost eventually logged me out & I have been unable to log back in....
Spotify & pretty much most music streaming services. I buy all my music directly from the artist whenever possible....
