Glitch Deleted All My work
While editing a document, it glitched, shut down, and deleted about 2 hours worth of work, seemingly irretrievably. For a product that I pay for, this is pretty unacceptable, and burying your feedback options behind a separate website and login only further shows how little you care about consumer experience.
My idea: if you want customers to feel like you actually care about their experience on your substandard product, don't force them to a separate webpage and make them log in again just to tell you when you mess up. Nothing more clearly shows that a company that can't care less about the users they exploit than making feedback difficult and cumbersome.
