Account Ownership Transferred but Cannot Use

[AlSanCarlos]

Our HOA has a Pro Zoom account.  The prior treasurer transferred ownership to me.  The prior meeting ID and PassCode that she setup do not work.  She cannot log into Zoom with her prior credentials.  I cannot schedule a meeting greater than 40 minutes.  Zoom says that I am on the Pro plan.  I had a free Zoom plan before the prior treasurer transferred the HOA Pro plan to me.  How do I access the Pro Zoom plan features?  It appears that I am on the free plan.

Updated information.  The prior owner of the Pro Zoom account was able to log off and log back in and schedule a 2 hour Zoom meeting.  So, it appears that even though I am the owner, the credentials of the prior owner still work.  How do we transfer and change those?
