Thank you for your feedback!
AddFunc Mobile Detect automatically stops redirecting once the visitor clicks back to the original website, as long as it isn’t from the same domain name. (If you are redirecting to a URI on the same domain name, you probably don’t need this plugin.)
In order to add any kind of back button to the website we’re redirecting to, we need to have control over that website and add it there. Generating such a button from this plugin (or from any redirecting website) would require opening it in an iframe. Then we can add things around the iframe and it will appear to be added to the website we’re redirecting to without actually having control over it. However, that would not be a wise solution for displaying a mobile site and this plugin is made only for redirecting to mobile sites. So that feature really does not belong in this plugin.
Perhaps what you need is an iframe redirect and/or to work out a deal with your advertisers wherein they have to add a back button on their site that shows up if the visitor came from your site.
I haven’t heard back from you on this. I hope my response was clear. Basically what you’re proposing would be outside the scope and workability of this plugin. Surely there is a plugin out there for your need, or there should be one. This is simply not that plugin, nor is it meant to be.
So if you would kindly and respectfully update or remove this review, I would greatly appreciate it. Anything less than a 5-star rating is a hard burden to deal with and should only be given where warranted. I don’t believe a 4-star rating is warranted when it is based upon an expectation the plugin isn’t design for (which I understand you may not have realized when you originally wrote this review).
Thank you in advance.
