This used to be my fave messaging app not until I've encountered a lot of unfixed bugs. In the midst of video streaming, when a person have seen and sent a message, it stopped and glitches- freezing on screen. There are times my I can't seem to sent a message and receives an error prompt. This issue have been happening to my friends too with different smartphone brands. Also disappointed that I can no longer send a file format (pdf, word, txt, etc.) and .gif format images via mobile.
