Pokepon gacha hasn't worked since 5th gym

I was able to use the Pokepon normally at first, but at some point in my playthrough, the lady started telling me it has been too short a time since my last visit no matter how long it’s been or how far I’ve walked. I think the last time I used the Pokepon was at the 5th gym, and I just beat the infernal cult and checked and the lady still tells me it has been too short a time… I think this is a bug?

Did u alter your computer time? That’s been known to screw up time based events iirc
