Hi @SFCJohnT,
Sorry to hear about the marketplace not working.
There is a topic in #bugs-and-issues that we like to have everyone use for this issue so that it’s kept track of and to help those with this problem.
Marketplace Greyed Out - Bugs & Issues / Miscellaneous - Microsoft Flight Simulator Forums
If not seen this, there is also an FAQ about it here:
The Marketplace and/or Online services are grayed out – Microsoft Flight Simulator Support (zendesk.com)
I’ll move your topic into the main topic.
Thank you.
