This issue continues to affect me as well. We need the ability to “Log Call” without it closing the open task. The button in the “Log Call” activity window only provides the option to “Log Call and Complete Task”. It does not matter what type of task it is, nor how the task was originally setup. Hubspot consistently wants to close the task when a call is logged, which is not a realistic or efficient workflow for many of us. Please fix this issue, which stems back many years.
