Can access paid content on desktop but not on mobile

My local Swiss newspaper is called 24heures.ch and is mostly protected; most articles have a “Abo” icon next to them that means you need a paid subscription to read the text in full.

On Windows 10 with Brave 1.9.80 Chromium: 81.0.4044.138 I can read the articles as if I was a paid subscriber.
On Android 8.1.0 with the same Brave version, I can only read the first few lines of articles.

Any idea why?
Thanks
