No default parameter for "Last Month" on a date range for a report. This becomes an issue when customers want a report run at the beginning of each month for the previous month-- You can set up a date range for 1 - 30th or 1 - 31st, but either way it will not decrement correctly for a month with a different number of days. Frustrating.
Can be difficult to modify reports -- at least more difficult that reporting software I have worked with in the past. Review collected by and hosted on G2.com.
