I've had this a lot with adopted storage (sd-card formatted as internal storage).Another strange problem :
Have regularly "Missing SD Card" : the SD is a Sandisk ultra 128Gb class10 (A1) a new one of course.
The SD card is treated as "internal" not external.
it's a Known problem ?
I try to do the same thing (as internal) with Lineage OS 17.1 latest ROM on an another Phone, same problem :0x
Set the SD card , data transfer , no problem.
Restart the phone (because i need to put a Sim)
BAM : "Missing SD card"
Look if SD card is well inside the SD Port, no dust, etc.... No physical problem.
Try to restart the phone : a notification say "Carte SD Sandisk" is missing and still remain permanent now
In the end I got fed up with it and just use it as external sd-card. Since then that issue never occurred again.
