Got ahold of one for testing. When leveling up, it has a flag disabled. Compared to Primeape evolving into Annihilape, there is a similar flag enabled. A lot of moves seem to track their use.
Since it's still there, it's probably as simple as activating it during an update. Funnily enough, stantler and regular Qwilfish have counters as well.
With the link shared by Mare the H. Zoroark, I think we can assume they're just going to activate the flag during a later update, and there's probably no way to bypass this at this time.
Something I'm going to try later, though, is the rare candy at level 100 method since it forces a check as well.
If it works, I'll update my answer (sorry. My state is having blackouts so I had to cut things short).
