So I just switched from Verizon to T-Mobile and received the identical phone (Galaxy Note 5) and now suddenly I'm having no success in using this app to transfer anything. Strangely enough I was able to put two MP3s onto the phone then suddenly all of the upload functionality ends. It can't be a restriction of file size based on the lite version because I was using it perfectly fine without hindrance on my Verizon Note 5 the other day ago. Perhaps it's some kind of difference in file structure between the phones? I'm totally lost at this point and any suggestions would be greatly appreciated.
