[TriLUG] ReCaptcha ( mobile ) issues

[Tim Jowers via TriLUG]

Hi Brian,

Sorry, no ReCaptha experience here but some ideas...'

Been a while since I messed with this but you can connect to the running
Chrome on an Android phone and debug. Sounds like maybe a javascript error.
If you are really lucky, maybe some missing js lib. In fact, there is some
way to run Chrome in a debug mode and see some output on the phone but I
found that to be tedious and close to useless. At a basic level, maybe you
would be lucky to attach an Android phone to a running Android debugger
(e.g. run Android Studio and plug in your phone on Linux and Mac, install
phone driver also if Windows) and see some useful output into the Android
debug log. Sorry I'm not up to speed on the iOS equivalent though maybe
just running xCode and then launching a Simulator and hitting your website
might reveal something.

My guess is the "white wash" is an attempt to reload the entire page. That
should not happen with a captcha. It should reload the DOM inside some DIV.
IMO. Perhaps there is something triggering a form post?  A simple bug could
be if you had something on your page triggering a form post - but not sure
why it would happen in a mobile browser other than if you had some
overlapping elements or something (assuming you tried running on desktop
with the browser resized to the size of a small phone and possibly other
phone emulation within a desktop browser).

Also, maybe you can try the chrome://inspect in the mobile Chrome browser
to see some of the chrome debugging web tool. Haven't played with it on
mobile but on desktop its a good IDE mix, as you probably know.

Sounds like a tough challenge,
Tim
