The only browser that I can get to open a console window on an iPad is the Opera browser. However there is no keyboard apart from the function keys making it unusable.
I had no luck at all with Chrome, Safari or Firefox. New tabs do open (if you enable pop-ups) but no console is displayed.
Please can you do some iPad testing. We would love to be able to fully support vCenter from our iPads – especially now the iPad pro is available.
