After the update two days ago my originally working well rift s encountered this problem. it requires me to reload the dash over and over. I did some tweaks and then my left controlled suddenly lost tracking, but the message of letting me reload the dash changed from popping up every 1 second to every 10 seconds. I had reinstalled the driver and unplug the cables but those didn't work. Sorry for my bad English. I had problems with my oculus rift and never get it to work perfectly. my new rift s did worked fine for a week and this problem happens. I sincerely felt desperate and needed help.
