I downloaded Messenger Lite because Messenger developed an unfixable glitch where people would be suddenly unable to message me, receiving an error claiming I had blocked them when I hadn't. And on Messenger Lite, I saw my "active now" list included my entire FB block list, regardless of whether I've had any interaction with them on FB itself and with their recent profile pics on display. Messenger Lite also lacks dark mode & audio/video calling. Both apps are broken, unstable and unsafe to use.
