Did you try all the normal stuff like
a) playing from Prime app on desktop to bless your IP?
b) clear temp/cache folder(s)
c) log out, then log back in to account for Prime in SF
d) try changing DNS to Google or Cloudflare if using ISP DNS
e) if using VPN, try NOT doing that?
f) what ERROR are you getting?
Nobody can guess why you are unable to access the platform, so specifying what you’ve done to diagnose issue helps. Working for me, in US, no VPN, GoogleDNS.
