Finally we have received an alert 6 days later. Proseries messed up & are asking us to now reschedule 4/15/21 estimates & cancel 6/15/21 estimates. Apologizing for the inconvenience is not good enough. Will Proseries cover interest & penalties for messing up for the 2nd year in a row? We can't charge our clients for this extra time let alone expect them to pay interest & penalty. Proseries response is beyond disappointing. The penalties will have to come from my pocket. I hope Proseries reaches out to me. They owe me an apology for their disrespectful treatment when I called to report this serious issue the evening of 4/15/21. The IRS ENCOURAGES electronic payments but Proseries is making it very difficult to implement.
