This app functions properly on my Android phone when it wants to. Calls to customer service, uninstalling & re-installing, powering off, restarting, etc. doesn't help. When doing any of that did help, it didn't last for long. It ran perfectly for a long time. IDK what went wrong. It doesn't seem to be associated with my phone or carrier because AM works intermittently on my Kindle Fire, Roku tv, etc.
