Board Game Arena

I have 5 location tiles. The ability says that when I have 5 tiles, I can put a cube as an achievement, which slides over the other cube. But it's not happening. Is there something I need to do to trigger it?

(I would include a screenshot, but I can't figure out how to do that either.)

I'd love to be added as a tester. Lots of plays both in-person and on the IOS app. (Or does that disqualify me? )
