Cron PHP Notice

Hi,

First off, love the plug-in, does exactly what it says without extra bloat.

Now, the reason I made this topic. On our site we’ve disabled the WP cron and made an actual cronjob on the server. This cronjob is currently showing a repeated PHP notice.

See below the notice:
PHP Notice: Trying to access array offset on value of type null in /wp-content/plugins/theme-switcha/inc/plugin-core.php on line 81

Currently this line is this:
if (!$options['enable_plugin']) return $current;

I believe this notice can be prevented if this is changed to:
if (!isset($options['enable_plugin']) || !$options['enable_plugin']) return $current;

Could this please be implemented?

Kind Regards,
JJ
