New tasks not saving when a start / end date is added
I run Thunderbird 115.18.0 (64-bit) with calendar and tasks connected to a NextBase Caldav account on the web. The Caldav then syncs with my Android phone using DAVx.
When I try to add a new task but without adding start and end dates it will initially appear to save and show in the tasks list. However this is lost following a Thunderbird restart. NB the task view is set to "All"
If I either edit the task to add start and end dates the task disappears from the task list. Similarly if I create a task with start and end dates the task does not save.
This issue only seems to have started recently as I have been using this process for a while without issues.
Is there a way to fix this?
