Bought RisingStar Cards But Can't Use Any? Remember To Update Them!

This took me way too long to figure out. And to be honest, the game didn't make much sense because the cards and upgrades that I bought didn't appear.

I thought it was something to do with not reaching a certain level but now it looks like a bug with Firefox, which is the browser that I'm using.

See the 'Click Here' button in the region I circled? Once you click that, the cards will be updated and you can equip them as needed.

Previously, my cards showed up in my collection but I was unable to equip or use any of them.

Hope this tip helps any new players out there struggling to understand how any of this works!
