@nebulon Thank you! I think I have something working in n8b, but hit a snag when trying to auth and I think I can make it work. Once the App Password portion is fixed in 9.2, if this works using n8n, I'll post the n8n template to accomplish this.

This is fixed with latest release now

So I was trying to reproduce this issue and got the .ics file with all those about 600 birthday events. However those all have the same UID, so they do map to the very same event in the end. Not sure if this was because of sanitizing the list or if this was related to some other problem. All in all I am not able to reproduce the disappearance though

So currently the app will resync the external calendar every 30min. This is just hardcoded for the moment and I am not sure if it is really useful to expose custom intervals or so, seems very geeky.

Yes that is on the roadmap and tracked at https://git.cloudron.io/apps/calendar/-/work_items/3 Lets collect requirements for this here in the forum though.

Forgot to mention, this is already fixed with https://git.cloudron.io/platform/box/-/commit/053f26cd02ccc0b5b840e7bf358fe1d47e1e4b75 but pending the 9.2 release

I started the update manually and the issue is solved. THX.

The app supports a caldav endpoints so if you have a system which can sync this into some other provider it should already work. Currently the Calendar app itself does not have any way to actively reach out into other services. I guess the question here is which part in your setup is the single source of truth regarding the events. That one would be the server and the rest become clients. Wondering what the use-case is to have two such event stores itself. (Same answer really to the contacts topic)
