Since a long time I am looking for a method to sync subtasks between my Nextcloud and my Android phone.
I am using the standard Tasks app of Nextcloud and tried different Android apps (including OpenTasks and Astrid To-Do List Clone.
None of these combinations work for syncing subtasks correctly. Apparently all of the three apps seem to use different methods to display and store subtasks.
Is there seriously no working method (yet) to sync subtasks between NC and Android??
