On my Xperia XZs with Android 8.0 I formatted the external SD card to be used as internal or adoptable storage. I had to use ADB to get this working. The system sees the storage, but I can't use it.
Total Commander only sees the internal memory, which is 20GB of 32GB internal memory. The 128GB external SD shows up as 256GB of which half is used.
How can I get the SD card showing up as internal storage?
