Anyone using DDI-Connect?

Does your church or related org use DDI-Connect (https://www.ddi.org) or have they in the past, either/both the legacy product and/or the NG (next gen) Microsoft Dynamics based product?
Can you offer any feedback on strengths and weaknesses as you’ve experienced? I only recently started exploring and I’ve found no offsite (third-party forums, including this one, etc.) customer/user reviews/remarks/questions. I’m guessing that’s because their target market is fairly niche (Church Extension Fund operations is a significant part of the product).
Thank you in advance!
