Message+ does not work on my new amazon hd 10 tablet. I get error an message that there is no data connectivity. No problem with data connectivity with other apps and signal is strong. I have tried all suggestions suggested on your message board (turn unit off/on, uninstall/reinstall, delete data/cache) and nothing works. I have also spent 3 hours (3calls) with techs from amazon. Can you offer any other solutions?
