Yahoo Messenger stopped working correctly on my MOTO x a few days ago. All it shows is everyone offline. So, I installed IM+ another instant messenger for android. Neither showed any contacts online. So, I tried it on my Nexus 10 tablet and got the same result. Anybody help me with any ideas. I uninstalled and re installed and did the whole bit. Doesn't work on 4G or wifi either. Been using it for years successfully until last week.
