I used to use Nextcloud News as well, but it stopped working for a while after a new NC version was released, some time last year. I installed FreshRSS as a temporary solution, but I never looked back. Yes, it’s convenient that you don’t need an extra service and that it’s integrated in NC, but FreshRSS is very customizable and has a much better user experience. You can always link it to Nextcloud as an external page.
