Link between sites in the App version

Hi all,

I am trying to link two different sites.

While with the browser version I am able to do it easily using a safe link, with the app, once i log-in and tap on the link i am redirected to the browser version (asking for credentials again) instead of remaining within the app.

I need to be redirected within the app without having to log-in again. Any suggestions on how to handle this situation? Thanks
