Nextcloud projects (or "lists") created in Planify only sync one way

[bipox]

Describe the bug Projects (and their tasks) created from Planify will sync to Nextcloud but not from Nextcloud to Planify

This issue has been mentioned by another user here (but in my case tasks created in planify do appear in nextcloud)

To Reproduce

1. In Planify, create a new project (I name it Test-project)
2. In Planify still, create a task in Test-project -> task is correctly synced with server
3. Now in Nextcloud's webapp create a task in Test-project -> task does not show up in Planify

• Same issue happens with modified tasks.
• "Tasks" app on Android, the Nextcloud webapp, "Errands" on Linux, all sync correctly Test-project between each other.
• Projects created outside of Planify sync correctly with Planify.

Edit: tasks marked as done works, but tasks deleted in the web app don't get deleted in Planify If I mark as done a task that has been deleted on the server the "progress circle" spins infinitely

Desktop (please complete the following information):

• OS or DE: Fedora 40 with Gnome 46
• Planify 4.7 (flatpak)

Nextcloud 28.0.5 running the tasks app version 0.16.0
