Hello! I recommend waiting a few hours and trying again. The server may be unstable.
If you use a browser other than Microsoft Edge, download Microsoft Edge from the link below.
https://www.microsoft.com/en-us/edge/download?form=MA13FJ
- If you already use Edge, go to Settings > About Microsoft Edge > Check for available updates. If the problem persists, download Microsoft Edge again and install it to repair the browser.
- Test on another device, such as another computer.
- Use a different internet connection, such as mobile data. Use the USB Tethering or Hotspot option to share your internet connection with your computer. Don't forget to disable Wi-Fi on your phone.
If the problem persists, you should contact Rewards support.
