Hello @Kdog22
As far as I could tell there is no known issue, can I know the model of RE, and how about the Led status on RE after set up ?
You could try some suggestions in thread below and let us know if it works for you:
Has connected to TP-Link extender but no internet, what can I do?
It is recommend verify your Wi-Fi password by forgetting your Wi-Fi network on cell phone:
Go to Settings-> WiFi on your phone, Tap (or Long press the router's WiFi name ->Forget / Delete the network )
Please reconnect to your router wifi and it will ask for a password, will it accept your router password?
