I was very satisfied with the features of this app. Particularly the inability to screenshot and alert on attempts. However, recently, it has been giving me the message, "error loading chat, try again later." Typically, message I want encrypted are of an important nature, so this is highly frustrating and unreliable. Obviously, I have to share the app to use with clients and I find the link to share and invitation message sent to be very unprofessional and a little embarrassing.

Not a lot of bells and whistles but does the job. However, in the last few weeks the app seems to be glitching more and often won't load conversations, almost as if I don't have Internet access but this is happening with the user I chat with as well. It's becoming so problematic that we're looking into another app

Lots of resends because messages don't go through. But then sometimes the message did actually go through, so you end up sending the message multiple times. I get a lot of notifications when no messages have been received. These seem like minor issues, but this is a messaging app that has issues sending and receiving messages... It also crashes a lot or will not load up, and when you do get it to load, all your messages are gone. Make sure you have a backup messaging app cant log in after update
