fenix 5x APAC not updating

Not sure whether anyone else having similar issue.
My Fenix 5X is not getting the latest update. 5.40 was released in Aug but Garmin Express only shows 4.2 till date. I have tried with webupdater without success. Tried to update to beta version by copying GCD file to \GARMIN\System_v***, for some reason the watch is not "picking" up the update file either.
