i had a similar situation. moved into apartment in august (purchased). next january i received abatements and abatements were assessed. no issue. january after that, i DID NOT receive abatements and abatements were assessed. cost me lots of money.

management company claimed they give forms at closing. they did not. no recourse available.

our board now mentioned possibility of abatements at board interviews.

also once a year we go thru those who don't get abatements and have management company send thru all forms (or a link to all forms). from there it's the shareholder responsibility - but at least they have all the info.
