Developer. Been using their platform for 5 years. Constant issues. Poor documentation. Unhelpful customer support. Their software team loves to replace rather than FIX their software on multiple occasions. Calling customer support is pretty much useless as you get forwarded a half dozen times. They ask for your information only for the next person to ask for your information again. The dashboard is a convoluted mess. Honestly, the only reason we don't leave the platform is because I don't have the dev time currently to switch our payment provider. No one in my org is happy with Square.
