GoPro 12 not recognizing the card as a V30.

I bought the 256G version of this card with my GoPro 12 on Amazon. Formatted the card in the camera. When using the camera a message comes up over 50% of the time stating to upgrade to a V30 card and my video stops recording. My older (at least 5 years old) SD v30 64GB cards worked well in the GoPro 12 and I never had the issue I had with the 256GB. I was traveling for over a month and could not return due to Amazon's return policy. I don't want to buy a new one since I can't trust that this won't happen again. It does function and record at low quality, but I don't need a card this size if I am recording in low quality - what's the point?

Really fast and convenient. You won't regret.

I picked one up on sale back when they were pretty expensive. They are ridiculously cheap now. It replaced external HDD, USB jump drives and other methods for transporting data. Never regretted it, had many uses and benefits. Still lots faster than my cloud transfers due to crappy AT&T service. Mostly copied data from wired connection at work to the card and used data at home. Faster use than many other methods.
