Twich not work with Safari
I don’t see the merit in bashing Anet for using twitch it is not Anets fault that it seems to not work for you. Not sure what your issue is twitch has worked fine for me for many months. Not to mention if your complaint is in relation to the videos that Anet is doing with announcing updates they also submit those on youtube after so there is that. Again I don’t really see the validity in posting something about how twitch is broken in a guild wars 2 forum even if it relates to the use of Guild Wars 2 as a streaming service.
Twitch is completely separate to GW2. Arenanet doesn’t have any ability to do anything about it.
Try using Google Chrome or Firefox instead… If you are really super insistent on using Safari then make sure you’ve deleted your cache, browsing history, cookies etc.
