I have the same problem. Since that update, I had to download the subsequent updates from the web and install them manually. It seems that no one at Asus solves this problem, there must be some problem with the serial number of our Zenfone 6 and the ASUS server so that it does not provide us with updates.
Hi, I have also this problem. The last update I received was .107. I am now on .127 to which I update manually ... It seems that I have to update to 137 manually too
