CalDAV sync not working as expected

[C-512L]

Version: 3.0.8 Source: Flatpak (Flathub)

Steps to reproduce:

1. Launch app
2. Add new CalDAV account (in case is provider specific, its https://fruux.com/)

Expected behavior:

Account gets added and available tasks list are show on side menu

Found behavior:

Account gets added but no tasks are listed on the side menu

Notes: Apparently although tasks are not listed, you can create new tasks lists but they will no be shown.

Following are the only relevant logs from running G_MESSAGES_DEBUG=all flatpak run com.github.alainm23.planner (They do not reappear when reopening the app with the account already added):

** (com.github.alainm23.planner:2): DEBUG: 10:56:18.616: CalDAV.vala:112: Adding task list 'b3297392896'

I just created a Fruux account and synced it with Planner, I can't report the same bug, try running Planner again.

I tried to remove all flatpak's data (~/.var/app/com.github.alainm23.planner) multiple times without result. Also tried to remove all GNOME Online Accounts. I will try on a VM to see if is distro-specific (which is uncommon for flatpak I suppose).

I don't know if I am doing something wrong here, but here is how I'm adding it:

[alainm23]

Try: Server URL: https://fruux.com/

[C-512L]

Try: Server URL: https://fruux.com/

I tried with the same results.

Something good is that I was able to reproduce the issue on a fresh and updated install of Pop!_OS 22.04.

Side note: I forgot to mention in the initial issue the OS/DE which I made it (Fedora Workstation 36, GNOME)

Hey,

Just wanted to ask if you found a solution to your problem? I have exactly the same and not only with fruux, but also with my infomaniak account (which I tried half a year ago).

I use Zorin OS 16.2.

I have the same issue, on Ubuntu 22.04

FYI seems like there is a solution: https://github.com/alainm23/planner/issues/897#issuecomment-1246689540

CalDAV support is under development for Planify, I will close this issue until the implementation is done. thank you.
