I don't even recognize this product any more

I took the most recent update - i don't recognize this product any more.  I have it linked to my fathom account and now I am having the most difficult time logging in to meetings i have been invited to.  My account doesn't permit live chat - wtf??!!!  this is not service - now if i don't use the right tags here it blocks me as well.  this is beyond frustrating.  PS have been a zoom user for about 8 years
