Words with Friends has been bumped to version 1.2, both the general and Lumia-only free versions. According to the store listings, this latest release addresses numerous bugs and issues to help improve the experience for players. Unfortunately, the update doesn't seem to have solved everything, if latest reviews are anything to go by.
Those who own Nokia Windows Phones are reporting improvements in stability, but those who have purchased the app on a non-Lumia device are still complaining about issues that were already present. This is a shame as it's a popular and well-loved game. Here's hoping Zynga get the problems sorted quickly in yet another update.
You can download Words with Friends for $2.99 from the Windows Phone Store (both Windows Phone 7 and 8). There's a free version in the Nokia Collection should you own a Lumia Windows Phone. Thanks, Sahil, for the tip!
