Don't use this plugin - It removes the custom site identity so the WordPress logo gets used as the feature image. It fails to deactivate.
Social Share does not change any settings of the website or something related to "identity". Still, it's weird how you claiming about an issue/problem but no support ticket submission for verification which should be the first normal step.
What exactly is the purpose of this review on this case?
I wont recommend this plugin to anybody who is willing to use it for facebook mobile. The plugin sends your visitors OUT OF THE FACEBOOK MOBILE APP to a new window without session in Chrome forcing the user to RE.LOGIN in order to share the content. Plugin says that goes well with Facebook rules but's not. In fact Facebook policy specifies that such way is agains't their rules because sends the visitors out of its enviroment to another window application making it dangerous or vulnerable to bad practices such stealing data. If you are planning to buy this plugin to maximize your mobile efforts, DON'T DO IT.. is expensive and doesn't work as expected. Is only good for desktop users.
Stops provides a such lies just to get a refund without a valid reason. The Share action is managed exactly like Facebook provides, based on the official script.
The Facebook share action is managed like Facebook recommends and it is exactly the same workflow into any share script/plugin.
Indeed, the plugin may be expensive for someone that tries to use the script for free but definitely not for what it's provides.
