Hello,

This addon is working perfectly for “desktop and mobile version of facebook” on any device.For sending invitation from mobile ,you need to use second option i.e Mobile users click here,user will receive invitations send by desktop version of fb,and mobile app on their facebook messenger and on their facebook app instantly.

If you use first option and see this message on any mobile device, i.e.”This dialog is not available on this device. API Error Code: 4202” is related to Facebook API.Main reason behind is facebook API not support this feature for mobile devices.As I mentioned earlier,you need to use second option i.e “mobile user click here”.

Hello friends,

webview app which was provided with wowonder script was very basic version! No support offer by wowonder’s author to this webview app and now,android app is removed in latest version of wowonder script,too!

For any kind of social sharing or messenger support,you need advanced version of android webview app or any app!If you need such support which is also part of customization,please hire any freelancer!

Thanks
