I had constant failures with my 32GB cards in multiple v2 and v3 cameras. It often took rebooting the camera 3 times in a row to get it to read the card. I figured it was an issue with the cameras or Wyze, or whatever. It was so annoying.
Then I bought SanDisk Ultra 128GB microSDXC UHS-I Cards (up to 120MB/s) and I have not had a single issue on my two v3 cameras. (didn’t install any in my v2). The performance of using the cameras (watching recorded video, etc) is so much faster than when I had with my 32GB cards. Plus, I love the length of video storage I get with the larger cards.
