Is the unchanged URL displayed in the category or in a search result? Our search is currently fairly broken and does not display most of the updates we do.
If it is unchanged in the category (and not only in a search result), please note that
a. all update requests are processed by volunteers as well, so it can take some time. So we can't predict how long a speacial request will take. Updates are processed with higher priority, but still someone needs to do it. ^^
b. if you chose to additionally insert a load of keywords in the description or do some other questionable changes, thje editor might have overlooked the change of URL and rejected the whoe request.
