Sandisk 1TB µSD

I have used a SanDisk Extreme 1TB microSD card in my old Motorola Z3 Play for 2½ years with great success. I transferred it to my new FP4 this week and the FP4 will not read it. It can see all of the folders under root but the contents appear empty.

This microSD card is C10, U3, V30, 4K, A2.
Occasionally, FP4 prompts to initialize the card either internal memory or external. I have selected external and it will not read it even after an apparent initialization.

I have put a 256GB Sandisk Extreme and the handset will successfully read it.

Is there a known issue with this 1TB card in the FP4?
Should FP4 read it?

Thanks.
