After Sim Update 3, there are no departures or approaches in the flight planner, there are no com frequencies listed for airports, and there are no VORs or NDBs active.
Detailed steps: go to the flight planner and choose departure and arrival airports (e.g. CYVR - CYYC); choose IFR low or high altitude, and no departures, arrivals or approaches show up in the menus. In flight aircraft navs don’t show any procedures, there are no airport radios (just a generic “traffic”), although there are centers. There are no VORs or NDBs either.
It’s very common for parts of an update to fail. Sometimes this results in CTDs. Sometimes this results in the sim not starting, or getting into an infinite upload loop. The nav data update didn’t download for you. Try restarting the sim a few times. Try checking if there is anything in Content Manager that needs updating. Try waiting a day or two
