If campaigns on Polygon or Binance Smart Chain (BSC) network are not loading correctly, you might need to check to change the public RPC URL in MetaMask via chainlist.org:
Network | URL | Preferred RPC URL |
Binance Smart Chain | https://chainlist.org/chain/56 | not specified |
Polygon | https://chainlist.org/chain/137 | not specified |
Not all public RPC URLs might give the result you expected, so if one does not work, please try another one.
If this solution doesn't solve your problem at all, please send us a request via the support widget.
Please also be aware that you have to select the new RPC URL in your list after adding it. Clearing cookies and cache in MetaMask might also help.
