Does anyone know why there’s no desire to see a working standard (protocol) for calendar/tasks?
It’s clear that CalDAV doesn’t function consistently across devices (and does seem to be dying as a standard). If you work across different devices/OS it’s virtually impossible to get things set up seamlessly. Companies and developers of task apps seem happy to create silos and not look at interoperability.
If you want to self-host, it’s too hard to do this and you really are limited to a tiny number of options.
Never had an issue with caldav and cardav. Maybe you are using broken servers or clients?
Even notes can be done efficiently on those standards…
But, hey, I am using only FOSS server and clients, maybe you referring to proprietary ones? You know, those who are mare by vendors who have no interest in interoperability?
