RSS feed does not show re-released Sol Press titles

[hasezoey]

I had noticed that with the RSS feed from https://api.j-novel.club/rss, no Sol-Press titles (like Why Shouldn’t a Detestable Demon Lord Fall in Love?! or Redefining the META at VRMMO Academy) show up, even though they are already released.
(Also their Part 1 being available also does not show up)

Using liferea as a rss reader.

PS: i had already mentioned this in the discord, but had not gotten a response, maybe because i wrote it on a weekend

PPS: i already know that those titles are different than other J-Novel titles, though they should still show up in the rss feed as "Ebook Release"

I think the RSS feed shows only events added to the calendar. Since Sol Press titles were never added in the calendar they don't show up.
