Some apps and some sites do not work well.
You could easily say that this is due to the pages or app itself and I agree. Still. I have to use some of them.
You might have enabled some pretty aggressive blocklists with nextdns. If you can't be bothered, Adguard DNS is more accommodating but configuration-less, give it a try [0].
As for sites, I use startpage's anonymous-view [1] or brow.sh [2] at times.
