I’ve notice in the system status box I’ve had weather failed several times , Global Server fail, API Service fail, and Live server fail several times. When something fails it’s only usually one of these and then it goes back to normal and then its goes back again so on son… but sometimes it will even switch for example it will go from normal to fail global server to normal to fail weather. I have an iPad air 2 btw.
The devs know, it is actively being worked on.
This is likely due to the servers needing more CPU and Bandwith mentioned in Notam Update #3. Check back in if you are still having any issues once the servers stabilize after the Infinite Flight Team tweaks things.
