Please note that we will modify the connection banner, so that it can be visible on the Host's side only (i.e. not display in your Viewer) and also we'll add the ability to pick the corner in which the notification will be shown. For more information please see this page.
In case if the user needs to click something underneath the notification banner, they will be able to change the location, i.e. the corner where the banner is displayed. In addition, it will be possible to hide the banner on the Viewer's side (i.e. it will only be displayed on the Host's side). Hopefully, both of these improvements will be available in one of the next updates.
Yes, the banner/alert can be clicked through. Besides, in the next update we are going to make it visible on the Host side only (Windows 10/11) and invisible in the Full Control window on the Viewer side.
