On PC #1, I updated MSFS 2020 using Navigragph NavData Center. AIRAC 2111 rev 2 installed.
On PC #2, I updated Little NavMap using FMS Data Manager. after the update, it shows AIRAC 2111 rev 1 in FMS Data Manager. I hover over that green label and a popup says “latest revision installed”.
Should I have removed revision 1 first?
