Research around users navigating native app then being redirected to a web page

I'm looking for some research on the following scenario:

• users are navigating within a native app - they want to purchase some addons
• They press on the get addons button and then they are then redirected to the website.

I was wondering if there was any research that currently exists on what users perceptions are to this and what the impact is in terms of trust (they are essentially following a journey to make a payment) and also cash of use.

Is this jarring to a users expectation and what are the emotions that result from this?

I know the best way to get this information is to user test and that is something we intend on doing, but for now I'm looking for some existing research or experience on this.
