I think you're confused. This is asking you to "delete profile" which is not your "account". All their screenshots say as much. You delete the profile from Chrome, not your Google account. Then you re-add your Google account as a profile in Chrome.
Please consider revising your comment because it probably causes more harm than good. Disclosure: I am in no way related to Videostream personally or professionally, I'm just a user who likes their products.
I have been having the same working/not working issues for the past 2 months. I've tried all the same troubleshooting steps mentioned and the only thing that seems to do the trick is a full reboot, both computer and my Samgsung SG4 phone.
This is very annoying because there doesn't seem to be anything changing on my Win7 system.
Can support give a full step-by-step process on what to do to get the VideoStream application to go back to normal operation without a reboot, and for god sakes, put it in a script that you can run easily from the Chrome-plugin if possible because the one embeded in the plugin sure hasn't fixed anything for me!
Include steps you can do with the Android App as well!
I tried absolutely everything. No luck. And I mean everything.
Frustrating because VS works fine on my other, equally configured Win 10 PC connected to the same router.
Anyway, finally threw in the towel and did a Windows RESET (with data kept). That did the trick.
But it's a burdensome solution.
@hitimahana This was my answer from the team on the same question on the 9th of November:
We've recently been getting a large amount of users with the identical issue as yours, all with the Chromecast firmware version 1.28.100555, which is the newest firmware update for Google's Chromecast. Unfortunately Google doesn't provide a method to downgrade the firmware of your Chromecast. The firmware version we know to work is 1.27.96538.
