I have a similar situation in my app, i solve it with a very simple solution.

If you want to "skip" a page in your backstack, place some logic in the NavigatedTo() function of that page.

For example: you can have a bool that you set to true when you post to facebook, and then place the following code in the NavigatedTo() function of the ShareOnFacebook page.

Here is pseudo code:

if (alreadyPosted) Navigation.GoBack();

The GoBack() function will skip this page and return to the previous one, the user will never see the page.
