Worked fine on my Harmony OS phone. It had numerous updates in the last couple of months but the last one really pissed me off. Messages telling me to get the Official version, not allowing me to register it all make for typical "Meta" P.O.S. Sick of these corporate buy outs to control what we get by people like CIA bot Zuckerberg. My phone uses Android and the sec required for this program, just not the U.S operating spy software Google.
Since the takeover of "WhatsApp" it has spent more down time and had more updates... WHY? If ain't broke don't fix it. Your lies about improving are just cover ups for the greatest data skimming company in the world... "Meta"
