The quota resize command only affects existing /etc/quotas file target entries, not new quota entries.

quota resize volume

Adjusts currently active quotas in the specified volume to reflect changes in the /etc/quotas file. For instance, if you edit an entry in /etc/quotas to increase a user's quota, quota resize will cause the change to take effect. The volume name may be omitted if the system has only one volume. quota resize can be used only when quotas are already on. Because it does not rescan the file system to compute usage, quota resize is faster than turning quotas off and then on again. quota resize will apply all updated entries in /etc/quotas; however, it will generally ignore newly added entries. A newly added entry will only take effect if the corresponding user or group has an active quota as a result of updating a file subject to default quotas.
