Because of a weak instrument problem, only OLS results are shown, which points to a need for caution in interpreting them.

Q Unfortunately there are no tests for a) weak instrument and b) over-identification of instruments in cluster-robust IV-Probit models.

Given the similarity of the estimates between the two instrumental variables, we conclude that our estimation approach does not suffer from a weak instrument problem.
