I try to upload by caldav using this app: https://play.google.com/store/apps/details?id=org.sufficientlysecure.ical
Then, I use davx5 to sync contact & calendar from Runbox with my phone.
The event where successfully imported in my calendar “runbox”, locally on my phone.
But for some reason, events are not uploaded to my online runbox calendar.
Also, If I create an event on my phone, it won’t be uploaded online…but If I create an event online, it will be sync’ed on my phone (so I assume the davx5 can connect correctly).
Did I missed something ?
