Add a 'Get the URL' button either on the 'Share' header button or in the dropdown menu.
Unless I am mistaken, you either need to disable Wiiwand or click on 'Read on Wikipedia' to be able to get the actual URL for sharing a wikipedia page on something other than FB, Twitter, Gmail, or or G+. I realise that neither of these are overly time consuming but having a 'Get the URL' button on either the header or in the dropdown menu would be a nice addition.
You can simply Copy the URL from the address bar.
WikiWand URLs work and are fully readable by anyone – including people who do not have the extension install.
that is sadly not the point. Wikipedia is considered trustworthy by many, a different link changes that. Your app is awesome other than that.
