What's going on with primal (npub12vk…pugg)'s messages notifications? The pink dot besides the envelope icon for messages shows up all the time, even when there aren't any new private messages. I click on it, clic on "Mark all read" and the dot goes away, but as soon as I go out of messages it shows up again. !¡ ?¿
