Rain Loop and Mail apps

Windows 10 64 bit.

Rain Loop and Mail apps do not work with Next cloud 17.

  1. Is there a web mail client for Next cloud 17?
  2. Is there a timeline for when either of these web mail clients will be compatible with Next cloud 17?
    Thanks

I have NC17 an they work for me.

I would recommend to verify your source of information, because both apps are already available for Nextcloud 17:
