Yes. I meant syncing contacts.
I use carddav from nextcloud.
I set up contacts sync from rainloop to nextcloud. Works good.
But it only works on 1 off the 2 urls.
mail.disroot.org works fine and syncs contacts (I set it up on this url)
cloud.disroot.org.... did not load the settings from mail.disroot.org because contact sync settings are not set up in the 2nd url.
I think the error seems to be that both rainloop instances save settings separated.
I only use one off both urls. So its not bad. And I could create an other app password in nextcloud to set up contacts sync in the other rainloop instance.
Just for me the settings did not get saved for the other rainloop instance. If you provide 2, sync the settings if possible. Maybe the error is on my site only.
