@giuse Thank you for the prompt update!
In my case, the site is hosted on WP Engine, with WordPress Update Source = Default (WP Engine’s Mirror of the WordPress.org update service – wpe-api.wpengine.com).
It would be interesting to find out how often WP Engine refreshes it’s mirror. Meanwhile, switching WordPress Update Source to WordPress.org (api.wordpress.org) seems to fix the issue.
@nengineer @mikefromnz Are you using WP Engine and it’s plugin repository mirror to update the plugin by any chance?
On my WPE hosted site, this only happens if the plugin source is WP Engine’s mirror. if I change the plugin repo source to the official WordPress repo, the plugin updates without any issues.
