@ChicsansI have an Amazon Kindle Fire that does something like you are reporting.
If I use the default browser "Amazon Silk" and try to go to the iStripper web site I get nothing but blank. I noticed that the browser was trying for the "mobile" version (
https://m.iStripper.com/auth/login) of the website, so I told it to ask for the desktop version (without the little m) and that came right up and worked.
Additionally, I have installed dolphin browser on my Fire and it does the same thing although Dolphin seems to have trouble displaying the website in the desktop version so I don't use it for iStripper at all.
I use Firefox mobile on my Android phone and that works fine with iStripper as well but that goes straight to the desktop version doesn't use the "m" version either. Maybe because my Firefox bookmark is synced from my desktop computers and that is where I made the original bookmark.
Not sure if IOS products do the same thing or not but that is what I see.
Hope this might help.
