My Question or Issue

I'm having issues with my Spotify;-; with storage, I have a SanDisk Extreme MicroSDXC 128GB A2 U3 V30 (bought the MicroSD card around Feb-March this year)

The download is on high for music

I have 500+ songs (over 3000+ songs it will change instantly on high or normal also if instant finish download and restart my phone it will be gone :_: I used to be able to hold 4000+ songs after 1-3 day 😞 but not anymore I am sad this issue does Spotify developer try to fix it or leave it as it is?) 

It happens when my phone is uptime for 3 days + then it changes storage to internal storage. (sometimes it change too if I turn off my phone for 2 hours and turn it back on it change to internal storage)
