Issue with RISE image carousel

I am seriously disappointed. The response consisted only of: "I’ve logged it as a possible software bug when uploading multiple image at the same time from the Carousel block."

A "possible" bug? Just look at this thread, it's clearly just a bug. I've had to simply redo the entire block and delete the buggy one, since I wasted 2-3 days interacting with "support" -- logging a case/documenting, trading emails, chatting with a chat rep who simply left me hanging, interacting with this thread, and then this final response.

I'm moving rapidly from feeling "sad" about the situation to feeling "mad" at the inadequacy of the process/response, and will indeed rethink my advocacy with clients who are Adobe shops without a concrete reason. Perhaps it's time to give their tool(s) another shot ... ?  :(
