Rewards app useless on series x

Same problem with the Microsoft Rewards app. There is no picture. Just a grey square that won't load. Xbox series X

I have same problem since changing to befibre ip

Got 2 series x and 1 one x all of them won't acess the rewards app since changing

Done all sorts to fix including conversations with befibre my ip address is showing uk

My brother took my series x to his house connected it to his virgin ip and loaded up the rewards app straight away

It can only be the connection between my xbox and befibre and it is believed that the only fix is for it to be a static ip address but at a cost

On XBOX Series X the Microsoft Rewards app hangs and when it does open minutes later, and you click on the weekly it gives an "oops, looks like something went wrong service unavailable" error with only an exit

Hi,

• Rewards app and points offers are available only on Xbox One and Xbox Series X|S consoles.
  
• Buying items from the Microsoft Store on Xbox or searching on Bing.com may not earn points in all countries or regions.
  

Still If you have any problems with the Microsoft Rewards app, or with earning points or redeeming them for rewards, go to Microsoft Rewards support

I posted in X Box Live Rewards Forum:
forums.xbox.com/.../4415522.aspx on 5th January, had nothing since, contacted X Box support and X Box Rewards team several times via twitter and getting either no response (X Box Rewards) or useless responses telling me to post in/tweet to different places
(X Box Support). Instead of passing the buck why not just sort this issue out for me please!
