This is the most incompatible with my sleeping schedule tennis event ever but I will still watch it. I've seen a few qualifying games but time to step up my tennis watching with the main draw.
Lots of viewing options happily.
Easy option if you have it - everything is on Discovery Plus
Free To Air option - They have lots of their own free streaming on FISU.TV.
Go to FISU.TV on your browser
Create a username/password
Once that is done, you can stream from your PC
Or you can download the app on all services - Ipad, Android, Amazon, Roku
Enjoy!
