[2021] Wild core store empty with nothing to buy

Good morning all,

Just started playing couple days ago, and wanted to purchase some skins earlier. However when i press the + sign trying to get some wild core. There's nothing showing up in the store...

I then switched from my phone to my ipad. Same thing still happens.

I've never had similar issue with other games

Does this happen to anyone else? or if there's anyway i could purchase wild core for my skins?

Thanks!!
