How stupid am I !!! That was it I was not up dating the version number each time... and I realised that if you try uploading both the 86x APK and the ARM APK it will not let you for some reason??
The 86x version only had the 370 compatible devises but the ARM version had over 11,000 so now I have uploaded just a new version of the ARM APK and it is working just fine...
Thank you "humanescape" for all your help..
