A big thank you to August 6990 for sharing a solution.
If you are encountering issues when trying to verify your identity in Google Merchant Center Next, where just a single-line bar appears instead of the steps, this guide will help you resolve that issue.
Go To Google Merchant Center and click on verify your identity here https://merchants.google.com/mc/products/diagnostics/accountissues

Now click on get started

A thin 1-pixel line will appear; you can now press F12 on your keyboard, which will bring up your developer tools, and select the element selector. If you are having issues selecting it, exit the developer tool and zoom in CTRL + to 175%, then open your developer tools again, and it’s a lot easier to select.

Now select the iframe and change the 1px height to 500px


Emmanuel, thank you for documenting this bug. The Payments-profile selector in my Merchant Center verification displayed only two thin bars, exactly as described in your article. An incorrect Organization verification was then initiated, all attempts were exhausted, and my account was suspended. I posted a sanitized description in the official Merchant Community: https://support.google.com/merchants/thread/463291883?hl=en
If possible, could you review it and advise whether this appears to be the same UI defect?
I also wrote a detailed email to your email address, [email protected], where I described how I found you from Ukraine. I think you, as a marketer, will find this interesting.
I have provided a reply in the community.
