I keep getting the error "Some changes are pending to be synced out, please try again" for the last 2 weeks when I try to refresh my emails!
Open the Email APP and tap the "Gears" icon on the top, Tap "Remove Temporary Files" "Refresh All Data" in that order.
It should fix the issue. Just curious is it an Yahoo email that is giving this error? When I get that error it is always for the Yahoo account only, The rest download just fine.
Odd, My comcast accounts usually work just fine,It's always the Yahoo one that does that on mine. It seems that the phone gets loaded with temp files and it should automatically delete them at some point but it don't. Glad I could help.
