Apps don't see adoptable storage anymore My adopted storage Micro SD card (Samsung EVO+ 64GB) doesn't get detected by any apps anymore, but it has worked with that same SD and exact phone (Moto G3) before.

I don't see how it would work either, since the /storage/emulated partition (yes, I highlighted the wrong line) shows that it is in fact only 11.8 GB. The only partitions that are close to 64GB are the /mnt/expand/* directories and those are not accessible. 

Is there some sort of "hidden option" that I turned off by accident?
I figured it out. In the "Storage &amp; USB" Settings, click the SD card and in the top right corner there are three vertical dots. Click on those and then "Migrate data". This fixed the issue for me.
