Is there something to do in order to make calendar sync (again) with iOS 16.2 ? Is there someone else impacted ?
We have users that are reporting that problem appears with their calendar after an upgrade on iPhone from iOS 15.6.1 to iOS 16.2.
Can it be related to Let’s Encrypt certificates ?
Version used is eGroupWare version 19.1.20200701 ; docker installation with Debian packages, connected to a MariaDB database running on localhost server. Reverse proxy is on another host running apache.
(My plan is to upgrade to latest eGroupWare 23.1 stable version, but I had to ask before going on to this journey.)
