@lyh16 It cannot be handled because it is a limitation of Android system regardless of any local VPN-based adblocker. If you want to filter HTTPS traffic of the Naver app, you need root permission of your Android system. Please use a web browser like Google Chrome and Mozilla Firefox.

Hmm.. But my observation is that I am having great ad blocking per se using the current configuration. As you can see in the screenshots, I see no ads using the given settings. However, my issues were that:

• News images are being blocked; but not the web pages themselves.
• Dark mode is being ignored.
• The NAVER app detects the Adguard CA certificate and gives me a warning, even though I installed the Adguard CA certificate.

If this was a system level issue, I would expect that the HTTPS filtering break the app entirely. However, since the ads are being blocked well but some user settings for the website being blocked as collateral, I assumed that this was an issue caused by some overzealous filters.

Did you enable HTTPS filtering for Naver app? If so, please disable it.

You can check it by navigating to AdGuard for Android -> 앱 관리 -> 네이버.

Done. The dark mode and images are back now. Thank you for the solution.

99% of the ads are blocked. The only exception being the grey ad area that can be seen near the top of the screenshot; where the ad image will not loaded but the ad text is still visible. These also go away if I swipe right and left to maneuver between different parts of the app.

As the issue is mostly resolved, I'm just curious about the reason behind this. Wouldn't the app have to break entirely if I'm having HTTPS problems? Then the rest of the web page is just falling back to HTTP then? What does HTTPS have to do with in-app dark mode and news images? The news text and thumbnail images loads okay.

The issue occurs because AdGuard for Android does not decrypt HTTPS traffic of Naver app. It means that AdGuard for Android cannot inject CSS stylesheet and javascript code into website to hide the leftovers and modify the webpage.

I guess that it depends on logic of an app.

Then the rest of the web page is just falling back to HTTP then?

I think that you can check it by navigating to filtering log of AdGuard for Android when the HTTPS filtering for Naver app is enabled.

What does HTTPS have to do with in-app dark mode and news images?

Maybe the app does not trust some images and CSS stylesheet if the TLS cert CA is untrusted.

So, I recommend using a web browser like Naver Whale, Google Chrome and Mozilla Firefox.

Thanks for the explanation. I'll consider this case resolved.
