@drq Indeed I should and I will! Thanks for the advice :D
Another question is how do I use it from my #Windows and mobile devices, #IPhone and #Pixel.
AFAIK there was a paid application for #cartdav and #caldav syncing for Android but I really don't want to pay for such a simple task. I guess there are open source solutions.
@cyrmax There's always https://www.davx5.com
