Navigraph Charts Not showing in the EFB

Navigraph Charts doesn’t show up as an app to be added or used in the sims EFB. I have uninstalled the Charts app and reinstalled it on my PC. I can open it on my desktop but it doesn’t show up on the in-game EFB. My Navigraph subscription is current and Navigraph Hub works fine. But, in-game Charts app doesn’t show up at all. Anyone with ideas/suggestions are appreciated.

Found the problem. The Navigraph plug ins were disabled in the Marketplace/My Library. How does that happen by itself??
