@ Mr. Ed.
According the label it is a high speed UHS I speed 3 only bus card despite being 32 GByte and I would be surprised if it worked. But a very nice card for high speed 4K UHD cameras indeed as indicated.

There is no indication for compatibility mode on it.

Very misleading as it even states SDHC. Sorry but SANdisk makes a real mess of their SD-Card labeling. They probably call everything up till 32 GByte SDHC (factory formatted FAT32) and 64 GByte and above SDXC (factory formatted exFAT) which is absolutely misleading information. HW reader slot/bus compatibility is the real important piece of information, which in this case was done correctly but I would hence call it also an SDXC card and not SDHC, but who is me if even a market leader does it differently!
@ Paolo
Looks like you got it formatted right as Internal storage also being a 32 Gbyte card.

But you can't use it as Portable at the same time and
you may never take it out again once being deployed as Internal.
Taking it out (even shortly) will cause all kind of instabilities and may cause loss of data, settings and APP's added.

You may need to do a full FW restore to get back to normal.
To use the additional Internal storage facility the new extra APP's must be installed on it or moved to it individually per APP. Not all APP's will support this. You will need to look at the forum/specifications of the APP for support and ways to achieve this per APP. As all my players have 32 GByte flash, this is the point where I stopped playing around with Internal Storage and can't talk out of own experience.
The
compatibility logo is a symbol that looks somewhat like @ with a speed indicator inside that symbol; this always being a 10 for hybrid cards. It is the "Speed Class" symbol on the Kingston example added (
=Works with conventional devices). Mr Ed's SD-card is exactly missing that specific symbol.
