Quotas take time to update

Hi all, I cannot find this or a similar question in the forum so here we go. I have a question with quotas, in particular a Pick, Group and Rank question. The idea is that every item within the question has a quota and once the quota for an item has been met then this item is not displayed. I expect the survey to be taken by multiple people within a matter of minutes. While testing it, it appears that the quotas take time to update (as I said, multiple Ps taking the survey within a short time, even concurrently) which results in items being displayed even if their quotas should have been met. I 've set up the quotas and the survey in such way so that if an item has had its quota met then the question is shown again but without this item (this is for situations whereby two or more Ps take the survey at the sme time). Any ideas how I can make quotas update instantly once the survey has been submitted? Thank you in advance.
