Recurrent transfers are confusing, no proper documentation on how to deal with them
recurrent transfer has a huge usability issue - exchanges are confused and thus having issues with supporting them, it's not easy to guess is a eligible transfer or not, documentation MUST be supplemented with clear instructions on how to handle incoming recurrent transfers. From user perspective transfer and recurrent transfer is pretty much the same, but in fact recurrent transfer isn't just a series of transfer operation.
