I actually find straight down to be really annoying and always struggle to keep water from streaming down into my eyes and face. I find the slight angle from a wall mounted shower head much more versatile for cleaning and comfort.

“Signal devs could take care of that”

They did like eight years ago.

I imagine that the signal devs viewed it as a similar concern as when you mistype your password the error message doesn’t give you any way to know if the password is wrong or if the account doesn’t exist.

If only some of your notifications are sanitized then those are the suspicious ones. If all of your notifications are sanitized then none of them are suspicious. Or, at least, they’re all equally suspicious, opaque, and unidentifiable.

Why do you so confidently assert things which you do not know but merely believe without checking?

Signal has supported this for many years. Users can choose full content notifications, name only, or no-content notifications.
