NextDNS kills my banking app

I have the same issue with one of my Telecommunication company's app and their chat functionality within the app.

It seems to be because one of the services used in the app is in one of the tracker blockers lists.

Without it, I can't use the app. I have alternate means of accessing these services though.

I'd rather NextDNS blocking the tracker.

You could do some research (logs) to see what is being blocked and add it to the allow list.

This will mean ANY website or app which uses the now allow list entry will no longer be blocked.

Convenience or privacy/security. It's up to you.
