I’m migrating from another Tasks/ToDo app called aCalendar Tasks which would sync with Google. I need to change because only the local Tasks app on my smartphone supports time-based due dates . Time fields don’t map to Google Tasks, & as such I’m unable to sync the time field to Thunderbird/Lightning on my computer.
I’ve installed OpenTasks in accordance with the DAVDroid app which specified that I use it. Apparently the Task items sync properly, just have a few details to sort.
First question is regarding when the tasks appear in my Thunderbird/Lightning calendar , but not on my Android calendar. When I look at the associated Tasks app on Android, I don’t see a list including due dates- just tasks. Ideally would like a list in chronological order showing each task’s start/due date.
Next, I notice on Android each task will notify upon start time & due time. However on Thunderbird/Lightning there’s no reminder at all. I have to manually edit it & set the Reminder field to 0 minutes  which then enables a ‘start’ time reminder- still not at ‘due’.
Lastly, whare is the tasks data being stored? I don’t see any of them listed on my FastMail account. Of course the calendar there doesn’t support displaying tasks like Google & Thunderbird/Lightning, so I don’t expect to see them inline on the calendar there like I do on Thunderbird/Lightning. I hope its actually there rather than on someone else’s server.
Thanks in advance.
