It would be best if you uninstalled (delete) any add-ons you don't use to help the overall store performance.
To uninstall an add-on you are not planning to use further, follow the guides below:
Go to the My Apps page in your store's Admin area (Apps > My Apps).
Locate the add-on you need to uninstall. Use the search bar at the top of the page for quick access. Type the request and click Enter.
NOTE: Please check for possible typos or spelling mistakes in the request. Otherwise, the search may respond with a zero result.
Click on the add-on name to see the details.
On the add-on details, click the Trash icon.
The add-on is automatically marked for deletion and added to the list of selected add-ons.
NOTE: You can add several add-ons for deletion, activation, or deactivation to this list and then apply the status changes simultaneously.
Click Apply changes. The add-on deactivation starts. Then follows the store redeployment process, which may take a while to complete. The changes apply to all selected add-ons.
Wait for the store redeployment process to complete successfully.
The add-on uninstallation process starts. Once your store has been redeployed, the add-on will be removed from your store.
