We have a web app being developed that will run on desktops / laptops (using Chrome or Firefox) & iPads.
On my iPad these work in the expected way; that is, a new Safari tab is opened & the appropriate content displayed. The customer says that when they close the opened tab (on an iPAD), it sets the prior window to blank.
Are there settings under Settings, Safari that control this?
In my settings (Safari) I have Open New Tabs in Background ON and Block Pop-ups OFF.
