Ratings and reviews

I am suddenly unable to send any messages. I am getting a message that says "Sender doesn't support replies" on all messages. When I switch back to the default messaging app I am able to send and receive perfectly fine. Edit: Y'all are the best! Thank you so very much! This is the only app I pay monthly for due to family issues and I panicked when it stopped working! Thank you so much for all of your hard work keeping this app up and running for us!

I can no longer send texts. Premium account. All contacts say "sender does not support replies" and there is no way to actually type in a text. Switched to stock Android text app and texting send and receive is working fine. Happened at a very critical time (family member in hospital). It just happened between yesterday and today and I didn't change any settings in phone or app because my last sent text was 3pm yesterday. EDIT: update seems to have fixed it. Thx.

5/5 as a blocker. 2/5 as a messaging app 3 overall It does what it says, blocks unwanted calls and text by number, and even by phrase. Sadly, the tradeoff is you lose basic functions like reactions to text and sending gifs, and it takes forever to send even a picture attachment, if it ever goes at all. No upgrades have been made to this app since I've had it, and I've had it for several years. probably not a viable daily driver for most users.
