Default browser app not resettable

Hey!

We are currently testing a few apps in Work Profile, for which we need 2FA. The second factor is a FIDO2 token that can be used via NFC or USB. If you have a FIDO2 token with USB-C, everything is fine. But we also have some with USB-A. If you don't have an adapter, you're more likely to resort to NFC.

Chrome supports FIDO2/NFC directly, which makes logging in quite easy. However, most web views cannot do this, and a passcode must be entered manually. The pure FIDO2 NFC tag basically contains a URL with the passcode. You open the webpage via NFC, copy the passcode, and enter it when logging in. So far, so good. However, we encountered a problem that prevents us from using the FIDO2 token via NFC in the Work Profile properly.

There are default apps for different categories such as browser, wallet, caller ID, etc. If you need to launch one of the app categories and there are several apps available, you will be asked which app you want to use and just for once or always.
The app preferences can be reset via the settings so that the query will reappear the next time. This works without any problems with “Home app,” for example.

But the Default Browser? No. The Browser app default remains after the reset. Even if a browser was set as the default and was deleted, it will just switch to another app and won't ask.

The problem with a permanently set default browser is that links from NFC tags are immediately opened in the personal space. If there is a copy & paste lock on the work profile, you cannot use the code. (Unless you type >40 characters) If you are asked for an app to open the URL, you can also select the browser in Work Profile.

Can anyone reproduce this behavior? Or does anyone know if something has changed for the Browser-Default in Android 15/16? On a device running Android 13, resetting the app defaults works reliably. It doesn't seem right that the browser default cannot be reset properly with Android 15/16.
