It will be nice to know the difference between recurring plans that we are still charging for and recurring plans that are no longer being billed.
Great news! You may see some new icons when you get to the recurring page in MX Merchant. We've added a new status to the recurring contracts page so you can quickly see which recurring plans are still actively running, versus the ones that have been paused, canceled or completed.
I've attached a screenshot for you if you want to take a glimpse but log in and check it out for yourself!
