Since the last update to MSFS I am only getting ground traffic.
I have updated FSTL to Injector 1.9.0 and Base models to v1.6.1 but still get this message on the drop down menu in the screen centre.
I cannot find anywhere to activate IFR/VFR injection.
HELP! This is driving me nuts!
FSLTL already announced over a month ago that, starting April 30, they would no longer be allowed to access FlightRadar24 data. As a result, live traffic injection has been discontinued. Since Injector version 1.9.0, it only injects static (parked) traffic. So what you’re seeing isn’t a bug it’s actually by design.
See here for more details and some solid alternative suggestions:
Thanks ChromedWings!
So we fly in empty skies now then. The other options in |MSFS2020 have traffic populating at Mach3 and joining sideways. Not immersive.

There are about 10000 messages on this over in the FSLTL topic. 
The TL;DR is use AIG, or use MSFS 2024 real-time traffic to inject FSLTL planes.
AIG is a free alternative https://www.alpha-india.net/ others are payware.
