Re: Why can't I upgrade storage?

Hello @aimtcb 

Try visiting Sunny Isles first. In lower right of screen click your Services icon (looks like a government building). When your Services panel is open, click Regional and scroll to the right if necessary to find Regional City Storage. You'll need to place that building in your Sunny Isles Region to add 20 permanent storage slots to City Storage. Repeat for Frosty Fjords to get 20 more storage slots.

Requirements to unlock Regional Storage:

City level (Experience Level) 25, Regional population of 5,000 and 5,000 in Regional Currency. 

I hope this information is helpful. 

Good luck to you!
