One of the big complaints has nothing to do with gameplay or performance, but missing access codes. Some of the people who preordered Stadia—a group referred to as founders, because they purchased the Stadia Founder's Edition—are still without their access codes days after the service launched.
"We're sorry for the delayed responses. We've identified an issue where a small fraction of Stadia access codes were sent out of order. That has been addressed. We've continued to roll out codes in the sequence in which we received your pre-order. We look forward to seeing you on Stadia," Google said.
The responses are not sitting well with some users. During an AMA session prior to Stadia's launch, Google hammered home that "Stadia IS NOT A BOX!" that users would receive their invite codes right after shipping their orders.
Part of the issue with the delay in receiving an invite code is that some users who jumped in early with the expectation of reserving a unique username may miss out.
"I am genuinely amazed with how shockingly bad Stadia has performed at my home over the course of many sessions," Tassi wrote, while noting his internet connection is solid with wireless speeds between 200-350Mbps.

"Even walking in a straight line was a challenge in the otherwise lovely indie game Gylt, the console’s only exclusive title," Park wrote.
There's also the issue of several missing features at launch, such as achievements. Google will flip the switch on those and other items as time goes on, but in the early going, it seems Stadia is very much a work in progress rather than a finished product.
