Blacklist Plus Pro SMS blocker not working with HTC One Mini
I recently installed Blacklist Plus Pro on my HTC One Mini running Android version 4.4.2. The call blocker works fine but the SMS blocker does not even though I get notification that it has been blocked. Questions:
1. Is it a known bug with Blacklist Plus Pro? Are there any fixes?
2. Is it a problem with the version of Android I'm running?
3. If so, which version works with this app and how do I downgrade/upgrade the Android version?
