They need to close all files before September so you would get soon. Maximum time I had seen on forum is 78 days. Another 6 days and you would get it for sure.
Don't worry friend you would receive in few more days, it is the normal wait time now a days, wait for the PPR is around 61-71 days and if you are lucky you would get it soon sometimes.
You would get it soon as it is sometimes taking 71 days and more. But, suggest you to go for GCMS notes to check section which is going on with your file.
