My GOG Galaxy account is synced with my Steam, Xbox Live Microsoft account, and shows I own 45 games. BUT the website account on GOG website says I only own two games "Gwent via iOS" and the "digital goodies for Cyberpunk 2077 pre-order".

I just bought Witcher 3: Wild Hunt on Microsoft xbox store. It shows up with 45 games on GOG Galaxy but not on the website. The website account says I only have two games.

WHY are the GOG website account and GOG Galaxy account not sync?

Attached Image Screenshot of both GOG Galaxy (Left) and GOG website account listing games (right). I am TransonicGenie6. Both the GOG Galaxy and website account use same email address too. Please help. Any assistance is much appreciated.

There's no such thing as "integrations" for the site. It shows you what games you own here on GOG and that's it. Size limit is <500 KB per file and <2 MB in total per post. Files larger than that get silently stripped out when posting.

What Ice_Mage said. Your GOG library here on the website is exactly that: games you own on the GOG platform. On Galaxy, the client, it'll count the number of games across all your linked platform accounts.

GOG is more than just Galaxy. It's a platform of its own, with its own library of games. Your other non-GOG games will not appear in your GOG library.
