18.0.3 is a security fix and it’s highly recommended that you update your NC as soon as possible. But it won’t fix the quota problem. As far as I understood it is planned for 18.0.4…
Running 18.0.3 too and no max quota number is displayed. Makes an Admin uncertain what a user’s quota is when you change it to something larger from the default. Glad to hear 18.0.4 will fix this bug.
