When dropping a task onto the timer the length is capped at 4hr regardless of the estimated time of that time task. If the estimated time is less than 4hrs the task is created with the actual estimated time, if the estimated time is greater than 4hr then the task is put in for 4h exactly.
When you drag a task onto the timer in Toggl Track, there is a 4-hour cap applied to the time entry that gets created. If the task’s estimated time is less than 4 hours, the entry will use that actual estimated time. However, if the estimated time exceeds 4 hours, the entry will be capped at exactly 4 hours.
This is the current behavior in Toggl Track. If you’d like to track more than 4 hours for a task, you can manually adjust the time entry duration after it’s been created, or you can create multiple time entries for longer tasks.
