Seems u have bought the whole stock. Ludia had some problems restocking because of covid-19, but they assured me they do everything they can, to restock as soon as possible, so u can spent all your money again. Rest assured, they don’t sleep before the offers are back, so u better pile up on your money, because there is a large shipment of card packs coming in soon.
I can see the offers. Have you tried to restart the game?
