The official Tapatalk app for Windows phone got updated yesterday to version 18.104.22.168. The app, which centralizes communications to various online communities, was released back in June for Windows Phone 7 and 8, and saw a fair share of connection issues to different sites. This latest patch resolves many of those issues, as well as some other minor bug fixes.
Windows Phone Central has also confirmed that, barring any major problems after testing the newest version, Tapatalk will see a reduction from its regular price of $2.99 to free soon. There is no concrete timetable for the planned price drop, as it is contingent on the conclusion of testing.
If you don't feel like waiting, you can get Tapatalk for $2.99 here.
Thanks for the tip, Garrett!
