iOS / NextDNS client blocks push notification token creation

Hi all,

I just had a very special issue.

After moving to a new iPhone, I had one app ("ifun") which was not sending any push notifications at all anymore.

Deinstallation & reinstallation of the app did not help, all notification settings remained useless.

Only when I disabled NextDNS, installed the news app, enabled Push notifications made it work.

Once I enabled NextDNS again, the push notifications keep coming one.

So somehow the NextDNS app prohibited the push token renewal / creation.
