Can treasurer get on checking accounts view only

I am a new board member 2-1/2 months and am treasurer. I have found mistakes our property management company has made. My concern now is they write, sign checks and move money themselves, and has been for years. We have had many special assessments and and monthly payments increased last 2 years from 645 to now 840. In last 2 years. Another board member who has been a board member for 5 years, President last 3, thinks our management company is great. She has closed meetings which I thought was illegal? I am having a hard time getting on our accounts VIEW only which also makes me more suspicious. Another board member, VP now, asked management company again about me getting on accounts view only he just told me the management company spoke with his partners and they agree it's too much of a risk. The bank said many customers view only. What should I do especially since found serious mistakes they have made since elected? I live in Florida andlooking for advise/Help please! Thank you!!
