is DocumentTracker reliable

Could anyone let me know if Document Tracker is fully reliable to use with 7.1 broker. If not, what are the possible issues?

Thanks for your help.

No, that former product was deprecated to “sample application” status a year or two ago and is no longer supported by WM / SAG.

If you are using it for simple sandbox testing it may work fine, but I would not rely upon it beyond that.
