HI @Jonas_O and @JFrentz and thanks for your feedback. This update is currently only available to a small percentage of our users, but I will soon post an official announcement to share the news more broadly with the rest of our community. But yes, as part of this update, we’re making Project custom fields available on subtask. This was a very popular request in the Forum (see Custom fields needed on subtasks) but I can totally see how it doesn’t fit every workflow. As always when we launch something new, we’re closely monitoring feedback so thank you so much for starting this thread. I have slightly edited the title of this thread to make it more discoverable to other Forum users and I’ll make sure to keep you posted here when I have an update on this feature request.
Hope this helps, but please let me know if you have any follow-up questions!
