Stuck in queue. Really need the build today.

Also, would the loophole corrections you mentioned cause issues with restartPolling() and didDetect callback? Is there any updated documentation related to these recent changes? Much appreciate your help.

I believe the only app using nfc on the development device is the app I'm working on. No other 3rd party apps are running in the background. Another interesting note, the device went to sleep and when I got back from lunch, after about 40 minutes, then nfc started to work again. Its like it reset it self. There is different behavior on different devices. For instance, I can have longer sessions on older phones like iPhone 11. Then newer iPhone 15 and 16 seem to have more restrictions as you suggested. ( especially iPhone 15 ) I will look over your suggestions.
