Convex useQuery Not Updating in Real-Time

Convex useQuery Not Updating in Real-Time I'm building an npm package (xerexjs) for real-time notifications in React/Next.js using Convex. The useQuery for fetching notifications requires a manual refresh instead of updating in real-time. Schema

export default defineSchema({
  members: defineTable({
    developerUserId: v.string(),
    notifications: v.optional(v.array(v.id("notifications"))),
  }),

  notifications: defineTable({
    content: v.string(),
    buttonText: v.string(),
    buttonUrl: v.string(),
    recipients: v.array(v.id("members")),
  }).index("by_recipient", ["recipients"]),
});

export default defineSchema({
  members: defineTable({
    developerUserId: v.string(),
    notifications: v.optional(v.array(v.id("notifications"))),
  }),

  notifications: defineTable({
    content: v.string(),
    buttonText: v.string(),
    buttonUrl: v.string(),
    recipients: v.array(v.id("members")),
  }).index("by_recipient", ["recipients"]),
});

Query Function

export const getAllNotifications = query({
  args: { userId: v.id("members") },
  handler: async (ctx, args) => {
    return await ctx.db
      .query("notifications")
      .filter((q) => q.field("recipients").contains(args.userId))
      .order("desc")
      .collect();
  },
});

export const getAllNotifications = query({
  args: { userId: v.id("members") },
  handler: async (ctx, args) => {
    return await ctx.db
      .query("notifications")
      .filter((q) => q.field("recipients").contains(args.userId))
      .order("desc")
      .collect();
  },
});

Client-Side Usage

const notifications = useQuery(api.notification.getAllNotifications, { userId });

const notifications = useQuery(api.notification.getAllNotifications, { userId });

Issue - New notifications don't appear in real-time; they require a refresh. - console.log(notifications) inside useEffect only updates on refresh. Troubleshooting Steps Tried - Restarting the dev server - Clearing cache - Checking Convex version (v1.19.2) Question Am I missing something to trigger real-time updates?
