Did the Mystic Cores disappear from the store?

As above! We used to be able to buy the mystic cores on a friday but they seem to have disappeared.

I have them in store, under the mastery tab. Maybe reboot game? Or look in the correct tab. You mileage may vary :-p

rebooted and they have appeared now. Thanks. May your next pull be god tier

I’m having the same problem, I’ve rebooted game multiple times and still no mystic core, any suggestions what to do next?
