A few days ago I started having errors on the web client. Right now, the big one is that my Home tab is basically wiped to zero. Random, Recently Added, Starred, etc., don't show any of my library. The one exception is that under "Recently Added" it will show an album once I've actually played it. When something does pop up on the Recently Added tab, the "date added" is the correct date. I've got stuff in there that shows dates of being added from as far back as 2013 and as recently as this week.
I posted about this in a different thread, but it seems like a separate issue. I do 90% of my browsing via the Home tab, so it really sucks not having it functional.
