I am using a V3 camera and do not need to take the card out to view play back and record. If you are using the battery powered WYZE Cam Outdoor you need to take the card out. For the V3 this is what I do.
Step 1.Open the events page on the app and tap on an event video.
Step 2. When the video starts to play or even when it ends just tap play back at the bottom of the page.
When the video is playing back from the SD card tap record button to start and stop, video is saved to iPhone/iPad photo gallery.
And Johannes Vincentinus Possum is back in action.
