Can't save on SD card

[Jamieenzo]

Hi, i've just bought a new 128gb sd card for my samsung galaxy s7. I've already cleaned my cache, uninstalled spotify, and formatted my sd card for the beginning. But now i've reinstalled spotify and in the beginning it recognises the sd card and is saves everything on it. But within a day, somehow spotify doesn't recognise the sd card anymore and the only way to let it recognise the sd card again, is by doing the whole cache cleaning and uninstalling spotify.

(I'm sorry for the bad english)
