Good dayRecently we have purchased an update of 6 licenses for microstation powerdraft, including an open access license subscription. We have 11 workstations, 5 with new version and 6 with old version.The workstations on which the 5 new versions are installed also have the old version.For the month of August we received an invoice for the use of 5 licenses. In the Monthly usage by user report, I see users who no longer work with checkouts.Where is the error? and we still have the possibility to cancel the invoice for non-use.Thanks in advance.
