Hi, long last and this has been resolved. Google Play have in the last few days released a build update.
Go to settings and build version should now be 7.0.17. H-all (0)
Mine was showing build version 6 before. If you are still on 6 just click on it and it will say downloading update.
We have four Kazam 348 and the Google Play download pending issue over wi fi has now been resolved with this long awaited update.
