DDOS's and site/infrastructure upgrades can cause websites to do funny things like not work. Hopefully that's all behind us now. I just checked RSS for my follows and it seems to be working fine, maybe just force refresh it?
@BraveDude8 I've been using this https://chrome.google.com/webstore/detail/rss-feed-reader/pnjaodmkngahhkoihejjehlcdlnohgmp for a long time without any problems. It still works just like always for few other feeds but has not updated the mangadex feed for couple days.
Oh, found something interesting. For some reason Ublock origin also hid the RSS button in the follow feed making it so that I couldn't re-add the feed to see if that would fix anything.
@BraveDude8 Seems like re-adding the feed fixed the problem even with the same software. Ublock origin for whatever reason hiding/removing the RSS link didn't help.
The RSS did seem to also work correctly with another program.
edit. The main culprit here I'd say was Ublock hiding/removing the RSS link making me think its completely broken or removed.
