      Due to sync source selection and vetoing, it is possible for a non-votable to block elections due to holding newer data no other voting member will be able to replicate. Since vetoing is only in protocol version 0 (PV0) this only affects replica sets which haven't upgraded.

      The obvious workaround to this issue is to update to protocol version 1.
