It’s a solid look, worth grabbing if you’re a atsApp user or you want to try out another messaging platform. The update isn’t yet in the ay Store, so grab it from A Mirror or directly from atsApp. y this matters: atsApp is one of the most dominant messaging platforms out there, with over 700 million active monthly users.
