Hello Michaela,

Thank you for reaching out to us.

The slow load can be caused by a lot of things - the number of appointments you have, the number of customers, the number of employees, etc. 

Other than Amelia, it could be caused by the amount of other data you have on the page. 
Are you on a dedicated, or on shared hosting? Can you increase the php_memory_limit on your site? 
If you're not sure how to do that, you can reach out to your hosting provider. 

Please check out our demo sites and see how the plugin should behave on a site with dedicated hosting and good server performance.

Hello Michaela,

Thank you for the update on this.

Please provide me a temporary WP-admin (administrator) user for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. 

We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course, we do not provide login data to third parties. 

You can write credentials here just check PRIVATE Reply so nobody can see them except us.
