Zero provenance of where each aid dollar goes. Does it reach the frontline, who's pocket does it go into? And why can't we track this information (at a high level)?
It's being tracked and there's been government reports checking if the money is being siphoned to corruption and so far not much has been found (except the usual low percentage of defrauding but that happens with anything).
You and I don't have access to it, it's just expected since it's sensitive information during wartime.
