Florida HOA Board meetings

Our community was handed over to Homeowners in December. The new board broke contract with existing Management company that controlled both our HOA and the Master Association. The original management company still manages the Master Association but now we have to pay two separate companies for our dues. Everyones mad as we were not notified or as members or consulted. Its a disaster. They send out emails to few regarding meetings to that day or just few days. I thought meetings had be posted and mailed out to all homeowners. And I thought it had to be a 14 day advance notice to the members? I believe the the New Management company and the new HOA Attorney that has ties to Management company are giving bad advice to board members including allowing the board to move out the Original Management company out club house breaking a contract and not giving the 90 day notice as stated in their contract. What is the proper notice for HOA meeting to members?
