There is a problem with the 128 GB card. I can read it, but I can't format it on Mars. When I try to format the card in the settings, the settings crashed.
I have now taken a 32 GB SD card. It can be formatted and also appears as an MTP device. Perfect.
Now there are no more errors under Calibre and I can transfer my books to the SD card.
I have now installed calibre companion on Mars and tried to open the directory on the external SD card. There were no problems with this under Android 6, but here under Android 8.1 . I only get an info for the path and no dialog box for selecting the directory pops up.
Is there any other way?
