So you can’t see the master addon element’s in your Elementor Page builder? It’s a common issue and it happens for database cache or some other technical issue.
But the solution is too easy. If you are facing this issue after the plugin update or installation then follow me.
Step 1: Login to your Website WordPress Dashboard Navigate to Master Addons and click on "Master Addons".
Step 2: Now disable any element first.
Step 3: I hope you can see the "Save Settings" button on top right. Take a look at the following image. Just click on this button.
Step 4: Now you can enable that element which you have disabled in step 2. Just enable it and save your settings again.
Now reload your elementor page editor again and you will see all master addon elements there.

Now I hope you able to see “Master Addons” element in your elementor element library.
