Hello @kiek
I noticed Realtraffic suddenly stopped working for me after I updated PSXT to 22.7 It was showing 'No Traffic' in the radar view. I found that only by switching the 'Simulator in Use' option in Realtraffic from 'PSXT (P3D/FSX/MSFS)' to 'LiveTraffic' did traffic populate inside ReaTraffic again, its quite strange but there was defintely no issue before 22.7.
Regards
