Using your solution of having to now re-download all of my files by selecting "Always Keep on This Device" will cost me my next 3 full months of data usage allotment on my internet plan. I don't think that you realize that I don't have any other option than a satellite internet plan with limited data. Living in a rural area I do not have broadband available. Even if I want it and want to pay for it, we simply do not have broadband. So my choices are use the 'always keep on this device' today and blow out my plan for the rest of the month or incrementally, over the next 3-5 months gradually re-download all of my files. This is unreal.
I will literally have to go somewhere like my library this weekend to access their wifi and hope that I can download some of the files to a flashdrive, although again, in rural communities they too have significant limitations on download speeds. Fast food restaurants sometimes have wifi available for free...I will need to scope out places in the county where I can tap into free access so that I don't blow out my data plan to access MY files.
Can you understand that this is just not right?
