if this is the thread to which you refer ... (

i use a real computer.
i tested using both firefox and google chrome.
even made the ultimate sacrifice and used whatever they renamed explorer in windows 10.
you didn't say which browser you use, which operating system, or whether you use a real computer vs. a mobile device.
