First of all I want to say thank you so much for this extension! What I especially like about it is that it leads directly to the message thread, even though all the other developers say that extensions can't do that due to the limitations of the Dashclock API.
I recently switched to Hangouts as my default messaging app. My city offers this service where you can text a bus stop number and you'll receive a reply with the bus stop times, and I take advantage of this service to test out messaging apps and extensions. For some reason when I receive a text message from the bus service, it displays the contact name ("Calgary Transit") and the message contents. However, when I receive a text from an actual person, SMS Viewer only displays their number, no contact name or message. I never had this issue back when I used my phone's default messaging app. Any idea what's going on?
If it helps, I have a Galaxy S3, but am running custom ROM Liquidsmooth 2.37 (Android 4.3) on it.
