Storage
7% used - 134 GB free
And when I tap that it shows:
7.65GB
Total used of 144GB
Internal shared storage
6.98 used of 16.00GB
SanDisk SD Card
661MB used of 128GB
(so sd card is not showing "Portable Storage" now)
When I connect via USB to my computer and Calibre, it only displays "Internal shared storage, 7.49GB free of 10.6GB".
The file manager on the tablet I use is "File Manager +" and it shows
Main Storage
7.5GB / 16GB
I do use MoonReader+ Pro on the Mars, and it's a great app, but I really like KOReader better. Especially when reading PDFs for the fact I can set the contrast darker on light PDFs. Can't do that with Moon.

Apps running on the device should be able to detect the primary storage without problems. There's an api call for that and should be used on 100% of apps. Maybe your FM still remembers the old config and needs a restart/reboot. I don't know.
Speaking about KOReader: it should detect the new partition and fallback to it. (You can check that going to about -> report a bug and look in the "crash.log" that the storage reported is something like /storage/ABCD-EFGH).
About how your computer programs or your computer see the storage: It is via MTP. According to AOSP the MediaProvider should still expose both partitions (the one in the internal storage and the sdcard formatted as internal - AOSP call that "adoptable storage"). Please check that with your computer (Linux/Windows). You should see an MTP icon on your computer FM. Double-clicking it should show you two partitions inside.
If you see both partitions then it is a matter of sending books to the second partition. I'm aware that calibre has that option for devices with more than one drive (like Kobos with internal and sd parts). Not sure if that applicable to Android/MTP devices.
If you only see the partition with 10GB free, I'm afraid that's another limitation on the FW. I'm sure it worked on Android 6 so, before reformatting the sdcard as external, please try to reboot to discard "unknown state" shenanigans.
