No issues at all. The support team is friendly and responsive and helped us in every way we needed. The platform has everything we need for our development needs - from testing to deployment, it does it all. I would like to mention how easy and fast the setup is, with only a couple of clicks, the platform was up and running. There are no other downsides as far as I am concerned. For testing or prototyping purposes, this is what we use. We have been able to deploy the system quickly to different environments without major problems.
