Hello mission-created,
Since you have posted the issue under Education hub(Free), let us remind you that for the free version the update will be automatically available in the Admin Panel > updates once the update is released.
In case you are using pro version and your theme license has expired then you need to repurchase the theme and use that license key to again activate the theme. After the activation, you will get the updates up to 1 year from purchased date.
Hope this clears the confusion.
Thank you.
Best Regards!!
