I commented 4 years ago: "When a keyword contains Chinese characters, the blocking does not work." I just paid for Premium and am glad to see this issue has been solved. I think it only lacks one feature that I want desperately – adding a "Delete" button on the incoming message notifications so that users can delete a message straightaway. And when I tapped on "Need help? Chat with us", it showed "WhatsApp is not installed", which was not the case.

This app worked really well until recently, perhaps after the latest update. Since then I would only send and receive approximately 50% of my text messages. It would also tell me that photos were not sent but in reality would send multiple copies to the recipient. I tried to uninstall then reinstall but that did not work so I have switched back to the message app that is defaulted on my phone. Very frustrating since it had worked really well for a long time.

Great app and support. 11/17/22 Update: I recently experienced problems sending MMS messages. Support and I worked closely together to resolve the problem. They quickly provided beta versions for me to test and I provided feedback. After a few iterations, version 15.0.23 was released that fixes the MMS issues! I can't say enough about how great their support is. 👍
