  1. BORG token no longer shows in Metamask wallet. This may be because the Mumbai chain rpc provider is unavailable. You can remedy this by redoing the steps outlined in this guide (easy way or manual way).
  2. Error when adding Mumbai chain. This may occur because the Mumbai chain rpc provider is unavailable, if you are selecting a provider from the list, make sure that it has a green check mark for both Score and Privacy. This will most likely occur when doing the manual way.
