We have just found our mistake in version 1.1.5, not updating profile images and Twitter user information of PopToo Friends.
The mistake was caused by conditional statements distinguishing Version 1.1.5 and Version 1.2.0 that were confused upon releasing.
Since we are developing toward Version 1.2.0, there are some cases which is only available if the condition for Version 1.2.0 is true. But this condition is not being tested during the development, and it caused some confusion in releasing Version 1.1.5 which should have excluded only Version 1.2.0 features, but did exclude some key processes of Version 1.1.5, too.
Our apologies to PopToo Friends, we should have been more careful about releasing new version. We will fix this as soon as possible and submit updated version to App Store.
Thank you for your patience. We appreciate your sincere support.
