Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble, Tom.
What you are trying to do is simply not an option. The silk browser does not have the capability of downloading items in that manner.
What you could do, however, is to visit that site on your computer. So long as the magazine issues are in a compatible format (.epub, .pdf, .azn, etc), then you can download them to your computer, and then transfer them to the kindle via usb cable. If you would like to confirm the file type, I can help you through those steps.
I am an independent technician and I've spent my personal time, unpaid, in an effort to assist with the question for which you solicited my services. This site works on the honor system, and to that end, I have prioritized working with you ahead of other paying customers.
Although you’ve already paid your fee to the site, I am only compensated for my efforts when customers such as yourself leave positive feedback for my work. Again I apologize there is not a better outcome here, though this is really beyond either of our control. I do hope you’ll consider leaving a 5 star rating for me, rather than “shoot the messenger”, so that I may get credit for my time spent in good faith to answer your question accurately.
