Unfortunately yes. They see too many requests from paperdelivery.co and block requests originating from that domain - they only want the google bot to crawl their site :) I think I have two options:
1. Respect their decision to not allow PaperDelivery to fetch that page.
2. Use a set of proxies and headless browsers or outright impersonate the Google bot to trick the news websites into allowing PaperDelivery to fetch that page.
Blokada isn't a serious security app. It leaks DNS connections over TCP (only handles UDP) and uses covert techniques to track users (generates a unique ID for every install and sends it tagged with the phone model every time one visits a blokada webpage from within the app).
Yeah, no where close.

Apart from usual suspects like AdGuard [0] and other anti-virus products:
Intra [1] with any adblocking DNS of your choice.
Nebulo: [2] A no-gimmicks alternative to DNS based blocking (their latest beta supports DNS over HTTP3 (QUIC)).
I use both: Intra has no DNS leaks but is IPv4 only right now and laced with analytics (the fork I developed/use is stripped off all analytics). Nebulo is lighter on RAM and battery and supports custom on-device blocklists (non PlayStore version).
