Not related to Stadia, but I had some issue with my Pixel 3a yesterday that it just stopped charging and had to get in touch with Google's support to try initiate a repair (turned out to be a software bug, thankfully). My learning is :NEVER , EVER, EVER fucking trust Google with your hard-earned money, ever FUCKING again. Even their customer support person did not know what is the link that you have click/form you have to fill to actually initiate a repair request and told me basically the process is not worth it.
