App is garbage. I have the Samsung S22 Ultra. Sometimes I receive messages, sometimes I don't. Group chats, individual messages, iPhone, Android...doesn't matter. I have done everything, every website or link suggests. Went to my service provider, everything there was clear and they couldnt help. Even went to Samsung, had them troubleshoot it. They REPLACED my phone. STILL have the EXACT same issue. There isn't enough room in this comment box to explain how horrible this app functions! Pathetic
