Why Adobe has discontinued A/B testing for Forms?

[jezwn]

I was going through the Adobe Documentation for A/B testing on AEM Forms it surprisingly caught me that they have discontinued the feature.

Any ideas why?

I recall a similar request was raised by another customer and it was concluded that this targeting uses mbox.js which was deprecated in August'2020, and further mbox.js reached EOL this February.

Thus, A/B targeting is no longer working. Hope this answers.
