Hello,
As we are currently running a beta version of the forum software, there are some new features. However, the new version has caused problems with the Tapatalk API, and thusly, both connections from Tapatalk and the WindowsForum.com mobile application are currently bugged. We do not have a timeline for this to be fixed, but it will be, however, I would like to apologize for those who use this app often. You should, for now, use the mobile web version of the site. I will post an update here once functionality has been restored.
