Enrollment has dropped nearly 4% in those areas covered by the Federal Exchange, but remained about the same in states that ran their own (e.g. California).  Meanwhile, a“Treasury watchdog” reported that the IRS overpaid the ACA tax credits by $3.5 billion in 2017.  The good news is that the total was actually $5.8 billion but they were able to get recovery on the amounts that can be recovered – but the rest seems to be lost.  Oops.
