This is a conceptual idea: after a sync, show a message bar indicator (for calendars selected beforehand), that X events updates, Y added, Z deleted. Then you can tap on this notification and get a more complete summary where it says “EVENT TITLE updated, EVENT TITLE deleted/added”, etc.
No peer certificate error even when selecting http
I get “E/A-Fehler: No peer certificate” even when selecting “http” (not “https”) for my server (ask me for an url).
It has a self-signed certificate, but should work with http.
Can you please send the URL to firstname.lastname@example.org? I have use http:// to test with HTTP only servers and I didn’t experience this problem.
You have a mail.
OwnCloud seems to redirect to https:// by default (or at least in your installation). So I will close this issue as a duplicate of issue #3.
