Yik Yak is dead.
Support for the app is gone. They only have 1 other review. What happened to this fun app? The people moved on. Let this thing go. Or, you could properly support people trying to access the app. No support or information as to why I can’t get past the verification screen, despite having a valid mobile number. It suggests this app is either a zombie, or a scam. Unsure which is worse.
