Thank you for your thoughts! I see the following scenarios:
When you get a Social Sharing link on a mobile device it would be helpful to see some content before you have to an app. A lot of users do not install apps only in order to check if the content is interesting for them.
I think the conversion rate (users which installs the app) would be better if they could first “test” the content in the mobile browser.
So - my two cents: It would be great if you would see the content in the web viewer on a mobile device with the possibility (banner) to install the app.
