Turns out when you use the 'To Do Today/Tomorrow' board in your dashboard, if you have a subtask due on a date, IT WON'T SHOW ON THAT DATE if the main task date is a different day. The subtask shows when the main task is DUE.
Who thought that this was a good idea?! I almost messed up such a big project deadline because of the subtask NOT showing on the date it was due but I luckily remembered and figured this out.
I discovered that if you create your own CUSTOM board, call it whatever, and choose 'Show subtasks' and choose to show only yourself, with due today, THEN it will show you your subtasks. Beyond angry with Wrike and this issue. As an example, I did this today and went from having 3 things due, to 9! I am blown away that this is actually how that board was designed. Please fix this.
