Man this sucks ass. F1TV pro was a good deal, especially considering the amount of options you got for the live stream. (commentary selection etc) Last time I checked you could not even get the British commentary on sky Germany. The german pairing was unbearable. What terrible news
I am not sure if about the current situation but there are two Austrian TV Streams.
ORF Sport and Servus TV - they used to have all races - commentary is German though.
I can give you info about a provider that offers full F1 TV access for 20-30€/year, I've been using it for a few years now. It's great and you can easily stream it on any device. Send me a DM if you want more info
