#1

Before using /e/ in a new phone, I’m trying to sync my contacts (or agenda) from my Google account to the contacts app in my ecloud.global account.
(And later, sync ecloud.global account with /e/ phone.)

On the Android phone
Installing Nextcloud app and link it with ecloud.global : OK
Installing DavDroid
In parameters of Nextcloud App link DavDroid with ecloud.global
Sync

Nothing appear in the contact book of ecloud.global
Where is my error?
