Yes tps is back on scrypt 1 But we do not known for How long. There is well an new key coming on. Maybe they have to change back to 1 in order to update all the official Via AU card's. And will go back to TPScrypt 2 once it's done.
But Mrev 2.14,Dragon cam, Humi TOH 3.3 Hot 3.0 are supporting tpscrypt 2
