Webview change after https

Hi all,

just a quick question without pasting all my code here, I have a webview which was loading http example just fine, however all I did was migrate my site to https, and now the webview is treating the url as external.

Obviously I checked for any occurrence of http in the code, but nothing, its just "example" The only thing I have done in the site is a 301 redirect from http to https, could that cause it? or anything else I need to do to have it see the url as Internal?
