It is difficult to say for certain whether or not the solution for the suspended social login problem will work for previously created accounts. It will depend on the specifics of the solution and how it is implemented. It is possible that the solution could be designed to work with existing accounts, but this will ultimately depend on the details of the solution. It is also possible that the solution could be designed to only work with new accounts, in which case existing accounts would not be able to take advantage of the solution.
