Canossa maintained a partnership with Leopoldina Naudet though their mutual esteem for each other did not prevent disagreements between their individual methods, which led to the dissolution of their partnership sometime around 1816. Canossa also tried to establish a male religious order alongside Antonio Provolo sometime in the 1820s but was unsuccessful in this venture. It was in February 1820 that she first met Antonio Rosmini and Rosmini's sister Margherita became a close friend of Canossa and joined her order on 2 October 1824. The death of Pius VII in 1823 halted work in the recognition of her order and she was upset that approval had not been granted since her meeting with the pope less than a decade before. Canossa believed she would have better luck with his successor Pope Leo XII and in September 1828 left to go to Rome to request of him the formal approval needed. She stopped over at Coriano to visit Maria Elisabetta Renzi and stopped at Loreto before reaching Rome in November. In the audience with the pope he asked her to present a shorter version of the Rule so that his approval could come quicker; he also appointed a commission that the Cardinal Carlo Odescalchi led to assess the rule and the request. This led to Leo XII granting approval for the order just before Christmas.
