Captcha solvers mostly have case sensitive option in their api.
You can use it but you might need to go custom with http client.
I'm having a problem with this captcha. Can anyone help me solve it (module or something)
Also having this same issue
get data-sitekey from html and post it to a captcha solving service with page url.
It will return you an id for your order.
Check that id like every 10 seconds, then when you get the token.
place the tokens inside h-captcha-response and g-recaptcha-response using javascript.
Then do the login, it should work fine.
This is for normal captcha but i think it should be just fine.
