Agreed - I'd rather them just acknowledge the issue exists, and say they're looking into it and will provide an ETA on a solution as soon as they have more information. And post an alert/banner somewhere about this open issue in some centralized place where any user would know to go look. That would be the logical and considerate thing to do. I don't care if they don't know why it's happening yet, or how long it will take to fix, that's normal and could happen to anyone. I just want them to be honest so I have realistic expectations.
