I installed Gran Turismo Sport on my PS4 today and after hours it still tells me that game data needs to be downloaded
I had heard that the download speed from PSN was throttled due to Corona
How long does it take to completely install all data?
Have you ever changed the DNS server?
I have a 500k line
