I got this SD card as part of the Zoom F8 64 GB Bundle. Funnily, this card isn't compatible with the F8 that Thomann bundles it with.
After formatting the card in the F8, I ran the F8's performance test on it. It failed it. Twice.
Instead, I swapped it out for the card in my H6, which worked.
I notified Thomann customer service of this immediately. Over ten days later now, they haven't done anything to solve my issue. And they still offer the F8 bundled with the non-compatible card. Strange.
