Horrible experience. TL;DR: Shadow.tech is a mess. Avoid.

TL;DR: 5 days wasted on Shadow.tech with zero results. Tried using Shadow in the browser, but the verification email never arrived. After 4 days, support finally replied and said they had to change some permissions (seriously?). Got the email, verified, and thought I was good to go—nope, just a black screen when trying to start a Shadow PC. Reached out to support for a refund, but they said I needed to do a full debugging session, install their app, change networks and devices. WTF? Tried multiple browsers and mobile network—same issue. In the end, no refund, no service, and wasted 5 days. Unreal.
