Feel free to edit this Wiki Post. It is not exhaustive, just what was randomly added between the appstore and github repos. Nextcloud 23 beta 1 was released on 10/12/2021. Continuing the discussion from Any apps not yet compatible with Version 22? Please reference those earlier threads for apps still unsupported in 21 and 22. Iโll do my best to embed that info below.
