Sorry about this. There are however a few different ways for support. Through the App Gallery there is a "?" mark up in the upper right corner that you could send the issue using the Feedback. On the details of the app in the gallery there is an "Additional Support" link towards the bottom that would take you to the developement page where you could put in a request that way and there is also an FAQ section that might have some answers for you: https://www.xeroxlegalpractice.com.
I recently purchased a VersaLink C405 printer for the sole purpose of using the Connect for Clio app. I was able to purchase and install the app and can sign in. However, when I attempt to use any of the functions of the app, it loads infinitely before eventually timing out. This is unacceptable and it is infuriating that the only way to access support is through this forum. I require immediate assistance.
