Last stock firmware got a nice bug works with sd cards.
Any sd card connected to my Z3 Tablet Compact mount as exfat_uuid. So when I use two sd cards simultaniosly (one inserted and one with usb otg reader) both are connected to one mount point.
This screenshot with only internal sd card inserted
And next screens, when I connect second sd card with usb otg reader
As a result, access to first sd card lost before external will be disconnected and device will be rebooted
So there is an clear bug with firmware that must be fixed.
The best way is to use sdcard, sdcard1, sdcard2... as was at older firmwares and with another brands/devices

At this moment found only one untested solution - use sd cards with different filesystems. Have a think that ext4 sd card will not mount to /storage/exfat_uuid and will use other mount point - cant test it cause have not tools to format sd in linux fs yet
PS: alsow reboot to got access to the internal sd is unneded. Just unmount external sd, disconnect it, then unmount internal and remount it.

That topic is near but not same.
Marshmallow devices as written in that topic use sd card path as /storage/xxxx-xxxx , where xxxx-xxxx - generated sd card pseudounique id/serial. I have same at my Z5 device. And such works is unbugged by default, when using different mount points for different sd cards.
But I have not Z3 to test the bug from this topic: when all sdcards use one shared mount point instead of generated unique ones.
So support team must review/check this bug presence with all Sony devices at Marshmallow OS I think.

Addition: bug present only at Z3
Z5 works with multiple external storages without problems

I have SD Card 64gb, currently it works fine. Also I have USB flash drive that have OTG, Sandisk ultra dual 3.0 64gb.
When I had Android 5, there were no problems in connecting USB and moving files between SD card and flash drive.
But since I updated Tablet Compact to Android 6, there appeared the problem. If I connect USB, SD card becomes invisible and tablet sees flash drive as SD card. Is there any fix for this bug?
