In standard Nav 2016 (W1 and GB), the OnOpenPage trigger in the To-Do Card has the following code (there is no other code in that trigger).
IF GETFILTER("No.") = '' THEN
CurrPage.EDITABLE := FALSE;
Do you know why that code is there?
Other card pages do not have that code, and it is preventing users from editing To-dos (actually, I found that on the To-Do List page, if you click the Edit button, the card opens with View and Edit buttons both greyed out; while if you press the View button, the card opens and you can then press Edit - certainly a strange "feature").
