Connection issues – Lumu Light Meter Review

Purchased item on BHphoto couldn’t get it to work on my older iPhone and new iPhone 11 max. Customer service has been a pain. I reported the issue back in January and still no follow up. The issue is the connection port doesn’t fully hold inside the lighting port falls off easily and doesn’t pair to the phone to sync and use app. I don’t know why I can’t get app and device to work together. Spent a lot of money on this and it have been a waste.
Review by doesnt sync with app on Lumu Light Meter.
