It's easy enough that I've been able get my team started with it without any training or support from their staff! There haven't really come across anything we dislike about this platform yet - everything is pretty straightforward once you understand how things work (which isn’t always intuitive). We're not trying to build an app ourselves so much right now but instead just using the templates they provide in order to help us make some minor tweaks here & there before releasing our client apps out into production later down the line.
