Calls connect 75% of the time (at best) and the app is still filled to the brim with UI bugs. Example: often, when I open a notification I'm transported to the right conversation, but at the beginning of the conversation history. This is a year back, and when I begin scrolling down the app hangs. I need to force stop the app and open it again to see the actual message.
It seems they're obsessed with adding new features (like robot voice fx for audio messages), but don't know to fix the important things.
Still, strangely enough, I continue to use it. It works, but has a ton of quirks. I use stock unrooted Android on a 5X and the other 7 or so people that I know uses Wire have all experienced the same problems.
