I am on an iPhone 12 on iOS 18.1.1. I did not turn off the ASIAIR after it failed to start a focus before starting to capture a target. In addition, the correct tab was selected to make sure it did try to focus. having said all this, I have captured three other images since this issue first started and all three went to autofocus before capture. I assume the issue was an anomaly, but if it happens again, I will send the log file to your developers. Thank you for your concern.
Cheers,
John
