....is Galaxy not showing the games I just purchased today? I bought DoW 2 for example and it has yet to show up in my Galaxy library for me to download, among other games I purchased along with it.

I purchased it several hours ago and still nothing. Is this isolated to just me or is anyone else having this issue? Because it would be nice if GoG would fix this issue.

Nope, not just you. Definetly some issues with galaxy today: not showing my recent purchases in the recent tab, owned games tab count incorret and not showing new games.
I guess the hamster escaped.

Lol thanks for the laugh. But yeah, someone definitely tripped over the cord because even GOG itself seems to be lagging or having update issues.

I submitted a support ticket so maybe something will get worked on hopefully.

Did you restart Galaxy after having made a purchase? Galaxy seems to only ever update the games list on launch and never again.
