Every once in a while, I face the same problem. Ad notification and reward stop and/or just don’t work properly and get fixed again all by itself. I don’t change a goddamn thing in my laptop or browser. No idea why it happens! last month about 1.1 BAT just disappeared from my wallet. if I accumulate the total value of BAT I’ve lost due to such problems combined, it would be more than 10 BAT. This is just frustrating! when things will be stable?
