Locks my iPhone XR when toggling flashlight – FLIR ONE Review

I just got my FLIR One and downloaded the app. I have iPhone XR, iOS 14.3. When toggling the flashlight function within the app, especially when turning OFF the flashlight I’ve managed to lock up my phone several times. The app freezes, the phone doesn’t respond to any buttons or swipes. After 5-10 minutes, the screen goes dark and I’m able to use the phone again. I’ve used the FLIR One 4-5 times and locked up my phone every time, usually after just a few minutes. I need the flashlight feature because I’m looking for air leaks in my basement. I will return the camera soon unless I can find a solution to this issue.
