Messages frequently not posting. you type up a message hit enter, and the message lights up in a white cursor box then disappears nothing posts. The other guy sees you typing, but then no message. Sometimes the message appears in a white cursive box and it does post it’s been happening for several days. I thought perhaps it was because I was signed on another device so I signed out of all devices and cleared cache. It didn’t help I’m on an iPad, an iPhone, and a laptop, sometimes using chrome. And usually the desktop site, but I don’t always notice which site I’m using.
