After using the app with no problem for over a year, it suddenly keeps asking me to verify, my number, then repeatedly asks me to enter a valid number. This is the same number I've used since installing the app. I can receive calls but can't initiate them. I tried uninstalling and reinstalling it, but have the same problem. I would have rated it a 4 or 5 before this happened, but it's worth zero stars to me now. Such a disappointment!

I've had this app for years and it was okay. I guess in the last update, some features were removed... I uninstalled it this morning and reinstalled it only to find out that USA is no longer in the list of countries, and I can't verify my number now. I also JUST checked the reviews to see that this issue has been going on for at least 3 weeks with no resolution. Your technical team sucks.

The features during the video call is great. I can send pics and chat with others while remaining in my call. I can set up a group chat and talk to more than one person at a time. The only complaints I have that made me rate it 3 stars is that my phone runs extremely hot every time I use this app and the call clarity can be terrible at times. Fix this and you get 5 stars easy
