First of all, thank you Kano for such a wonderful pool. I'm here since January and haven't had any problems till some days ago. I have two S7s. They both do 5Th/s in bitmain monitor. So in total 10 Th/s. And it was 10Th/s on kano.is But few days ago my speed droped about 1 Th/s on kano.is But in monitor it is still showing 10Th/s total. Where could be the problem? P.S. the speed dropped on 22 Feb
