We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Unfortunately restricting submissions will affect the whole form. You can use "Strict check" or "Loose Check" this will limit submissions through cookies or checks IP but we don't have feature that will set certain number of submissions per state.
You can also enable submission limit but this doesn't check whether submissions are coming from a certain state or place. Once the limit is reached this will disable the from.
