@SimSeeker Hello! Please double check that you have enabled the online features in your game options. Click the three-dot menu in the upper right corner of your game, click Game Options, click Other, check the box next to Online Social Features Access, and then click Apply in the lower right portion of the window.
EDIT: Once you have verified that you have enabled the online features and you still can't get to the Gallery, it's possible that your antivirus software is blocking TS4. You may need to add exceptions. If you're not sure how to do this, there are instructions provided by AHQ Hero crinrict at the below link.

Please come back and update whether any of these worked for you.
