I can confirm the problem regarding 7.0.1.8. and Scream 2022 (location Austria and premium account).
It’s weird. Scream 2022 in Austria offers no German audio. However with VPN via Germany it offers German 2.0.
But it differs, most videos offer German even without VPN in Austria, some only German 2.0, some German 5.1 (and some even H265, but only with VPN via Germany). I think it depends on which German format P+ provides
I could not identify a clear pattern for this behaviour, but it seems, that only a few videos are affected by not offering German at all. Maybe the video data could be different in Austria and Germany and SF can’t handle it.
However, downloads in Austria with 7.0.1.8 work eventually, but unfortunately most P+ Downloads from Austria loose the audio after a few minutes of playback (with any ffmpeg version). Using VPN in Germany on the other hand provides flawless audio. This could be an indication, that there might be a different dataflow in Austria and Germany indeed. But I am only a gessing amateur.
So the last fully working Version for P+ in Austria is 7.0.0.9, at least in 540p, but with German 2.0 audio (for Scream 2022)
