Ive been doing ss last 3 days and portal spawn rate was great for me ( usually every second or third boss )
But those who said its normal spawn rate hope you say that based on your experience after the last update.
Altho, 1 hour before update i was running there and no portals at all so it continued after the update.
Imo I think they did something it cant be bad luck for hours lol
