It is very likely that you have been cheated, but it does not rule out that it is a software problem. Try reinstalling and logging in again. There are many dating websites and apps now. It is easy to register. After opening it, you will see many photos and general information of MM or handsome guys. From time to time, the opposite sex will greet you, but you will find that you can't send a message to reply at will, and you can only choose the text provided by the system mechanically. Next, you will be prompted to upgrade to become a member, with a monthly subscription or something, and chat with MM/ handsome guy for free. Someone broke the news before. It was a lie. There are countless such dating software. If you want to make friends to pass the time, WeChat is good. Although you don't use it much, I recommend you to try it.
