@miranda Yes, there are so many things I wish WIX Booking would include so I can keep clients all under the WIX umbrella linked to all the other apps on the site. I also hate to see links out of the site or code from a third party sites plugged into the WIX site and looks so alien within the website, adding to that is the double membership on both WIX and the third party site is a nightmare to explain to members, but at the moment WIX booking still got some improvements to do to allow all the features we need in it. I think the product development team in WIX do listen to our calls for feature requests, so in time, all that we want and need will be there, but until then, we will have to compromise on using third party software with some clients.

What a coincidence indeed. It is quite a common last name here in Japan though.
