Hello, I work with the Citicen Developer and have a working app with which I read tags via the nfc function. The app has been running for two years without any problems. A week ago I did some of the work on the app and published it afterwards. Then the NFC reader no longer worked. There was no error message, but after pressing the NFC read button, the iPhone button of the NFC reader no longer opened. After a few attempts, I found that other old apps still work with NFC. After I had also opened these in the PowerApps Studio without making any changes and then republished them, the NFC reader no longer worked either.

Hi CU18100801-0,

I think there must be some updates to the NFC functions. I recently answered a question relating to NFC which might be helpful.

Can you share a bit about your use case so I can try to spin something up and help you.

Kind regards,

Nandit

Currently it is like this, if I open a Canvas app that runs in the Powerpoint app on my Iphone with an NFC function and I open and publish this app in the Powerapps Studio, the opening of the NFC function on the Iphone no longer works.
In this case, however, I did not make any changes. If I publish an older version outside of the Powerapps Studio, NFC works again. When I open and publish the same app in the studio, NFC is again not functional

as soon as I publish it here, without change, NFC no longer works

That would be the screen that should appear on the iPhone.

This is a known issue in the Power Apps studio that is fixed in the 3.24102 version. This is currently not the version that will open, but it should be available in the version selector (Settings -> Support -> Authoring version -> Edit). Once you open the app in that version, save and publish it, then the ReadNFC function should work again.

Hope this helps!
