We have been experiencing numerous errors with this plugin. From API Heartbeat error messages and NOW Libra y Conflicts with Google Analytics plugin (Google Analytics Dashboard for WP) In activating GA we noticed slow-load issues and went to general setting and noticed message that dev says is plugin conflict . We narrowed it down to Appointments+ - WE need this resolved ASAP...the client needs the Appointment function for scheduling Domes - but the app stops working....at various times - even with the GA plugin NOT activated.
