Fallback to V2 / Challenge

[mruknowme]

In some cases V3 maybe failing consistently even with threshold below 0.3. How to implement some sort of challenge fallback? For example, after a few failures present with a classic V2 type of challenge checkbox/pic selection.

Thanks in advance for any pointers.

Is there any guidance on how to do this in general? If there is any documentation, preferably from recaptcha, that this is a supported scenario and how to implement it we can look at adding it to this project as well. But if this is not a supported scenario from recaptcha, I don't think we will implement anything special here as we only include officially supported features.
