Received email Incubator them update available but wordpress not saying it needs updated

I received an email indicating there was an updated download for Incubator Theme. I downloaded zip file but now when I check in WordPress, it does not indicate there is an update to be done.

I have not imported it yet but not sure why the THemeforest/codecanyon would say there is an update but Wordpress would not indicate this to update. Please advise. Thanks

If you purchased the theme from Envato market then to get one click update features you can use Envato Market WordPress Plugin. This plugin helps customers receive updates to their premium WordPress Themes & Plugins purchased through Envato Market (ThemeForest & CodeCanyon).
you can download the plugin from here:

Using this Envato Market WordPress Plugin you will see:

  1. Latest version (need to update version) number
  2. Details view option for the latest version

You can check your theme current version from wp-admin => Appearance => Themes and can compare the latest version published in Themeforest (theme page change log).
