One of my XenForo forums deals with Windows Phone 7 devices. I have it set up to support Tapatalk. They don't have an official client, but there is an app called Board Express that supports Tapatalk. Now, here's where things get tricky. The Windows Phone Tapatalk forum app Board Express does not support XenForo. I've been in touch with the developer and he's indicated the following as a problem. I'm not a developer, but was hoping I might be able to offer him a solution based on feedback from developers here on the XF forums.
Any suggestions that I might be able to pass along?
A bigger problem is the wrongly set standard cookie domain set by XenForo. Windows Phone 7 has a very secure implementation of cookie handling, which is ignoring all cookies with not correctly set cookie domains. I’ll have to check how this can be solved. Somewhere in XenForo you should be able to change the cookie domain.
