I just went through that with a Pixel 2. After 4 phones, the original one started working - by itself. (They sent me new ones, but I didn't return any for about a month.) So I know the problem, I know the frustration, but neither Google nor I know the cause of the problem. (As soon as my original one started working, they stopped looking into why it had failed.)
