You have created a Tile or other type of access within SAP Hybris Coud for Customer Ext App, to open an external link.
When you open this link, the VScroll and HScroll DOM elements are not seen in the Windows C4C app, but when you test the same on the IE browser, these two elements are visible.
Neither VScroll or HScroll are available within Windows "InAppBrowser". As "InAppBrowser" is provided by Microsoft, we have no control on it.
No solution can be provided by SAP about this issue. We just can confirm that for iOS devices we do not have this issue and scroll works fine.
