1) Yesterday may not have been the only time, but it's been YEARS since Lacerte had an issue on filing day

2) Thompson Reuters had a similar problem on 9.15.20.

3) My Lacerte customer ID is FIVE numbers - so I've used Lacerte for longer than I want to admit 🙂

Good luck with finding ANY software in this day and age that doesn't occasionally have issues.  Yes the customer service/support function sucks & has gone downhill, badly downhill in recent years.  The software is still great.

YMMV
