I have the same problem with my iPhone X basically I get the same error message as the screenshot, and another problem …
I bought two iXpand Mini when I was on holiday in Hong Kong thinking I would be safe with a product from a big brand like SanDisk, however, I stay in Singapore, and when I tried to fill up the RMA form, it says country not supported.
How can I get my iXpand Mini fixed via RMA?
Thanks a lot!
