Hi,
I have the same problem. But I cannot use the Gmail solution because I leave Google.
For this I work on NextCloud but for tasks, contact and Calendar I try to connect as is describ here but nothing appen… I try to enter the credential by myself and still nothing.
I also try in Evolution and it’s the same.
I try to delete and install again the app Nextcloud and Davx5… still nope…
I try every part with different adress:
https:/ /mynextclouddomain.com
https:/ /mynextclouddomain.com/remote.php/dav
If someone have any idea, I keep trying… the picture are here
Thank
