Cannot expand

My game is not giving me the option to expand and I am not sure if it is because I do not have enough coins or neighbors to do so. However, in the past, even when I did not meet the requirements to expand, I was at least able to click on the expand option. I do not even get that option anymore and I am not sure how to fix this issue.

Can you provide a bit more information about this for us please? What size is your board? Maybe a screenshot of your store? What device do you use? Game version? Neighbour count? I might need to send you to Support, but if you can let me know a bit more about the issue then I'll know how best to help you.
