Unable to format my Sandisk Ultra Plus 16 GB MicroSD

Okay, I returned it and got another of the same card.

I now have different issues with this card.
First, the Windows Format Removable Disk doesn’t even know the capacity to it. Nonetheless, I can’t format it.
SDFormatter 4.0 wont let me even let me attempt to format. the Format button is disabled. It just says “This drive is not supported”

If I try to insert the MicroSD card into my MicroSD USB reader and connect it to the computer, it doesn’t detect it.
If I insert this card into my old smartphone, it reads it correctly and stores files just fine. However, I don’t use this phone anymore.

What is going on?
