Unsolvable ReCaptcha v2 Invisible


New member
Hi, the other day I came across ReCaptcha v2 Invisible, which is not solved with Decaptcher, I am using provider 2Captcha, the problem is reproduced only on instacart.com
How to reproduce:
1. Open the page instacart
2. Click Log In
3. Enter credentials and click Log In
4. Having received the captcha, we send a request to the Decaptcher:
Using Ruby and REST API
#### The rest of the code
curl.url = "https://2captcha.com/in.php?key=#{API_KEY}&method=userrecaptcha&googlekey=#{sitekey}&pageurl=#{url}&invisible=1"
#### The rest of the code
curl.url = "https://2captcha.com/res.php?key=#{API_KEY}&action=get&id=#{action}"

or C# SDK
ReCaptcha captcha = new ReCaptcha();
// The rest of the code
Note: The captcha on the decaptcha's side is solved, the token comes
5. Insert the token into //textarea and execute the callback

document.getElementById("g-recaptcha-response").innerHtml = "Decaptcher token over here"
___grecaptcha_cfg.clients[0].B.B.callback("Decaptcher token over here")
// .B.B. sometimes changes
6. The form is submitted, but the instacart server returns an error in the graphql response. It looks like the token from the Decaptcher is wrong
And so it is constantly, however, the captcha can be solved independently and in this case everything works. You can also open another browser (with a different User Agent, Cookie, Proxy, etc.) instead of Decaptcher, solve the captcha there and copy the token from the response 'https://www.google.com/recaptcha/api2/userverify?k=6LeN0vMZAAAAAIKVl68OAJQy3zl8mZ0ESbkeEk1m', everything also works. It feels like the site can recognize that the captcha is not being solved in the browser. I tested 2Captcha on other sites, with different captchas, everything works without problems, problems are encountered only on instacart.

What has been tested:
1. Different parameters in the api request - invisible 1/0 , enterprise 1/0, userAgent, proxy etc.
2. Various ways to submit a form, via a button, callback, javascript
3. Solve captcha yourself in app CaptchaBotRS
Anyone have any idea what the problem might be?
