Issue with content display +syncing data across devices or database

Help
1

I had a problem with my project. I asked v0 to add a dashboard so I can manually make edits to the website, like post articles. I’ve noticed that after posting an article, the contents of it (the text) wouldn’t appear. I’ve asked it to resolve the problem twice, but it just wasted my credits by saying that there was no issue. I then discovered a bigger problem after visiting the website on another device, and it hadn’t saved any of the changes I’ve made from the dashboard, only the ones I told v0 to make to the website’s appearance. is v0 able to make a dashboard that I can use to make edits to the website, which can actually update in real time?

data won’t appear on other devices when they’re supposed to, and on the main device in which they appear, the content or text wouldn’t appear on the page, but would be visible when I inspect the page and check “console.”

There is no issue with deployment, only with the data visibility and showing across devices.

Hi Tove,

Yes, v0 can help build a dashboard/admin UI, but for edits to appear across devices in real time, the content needs to be saved somewhere persistent, not only in browser state.

From what you described, it sounds like the article text may be stored locally in the browser or only in temporary client-side state. That would explain why it appears on one device, disappears on another device, or shows in DevTools/console but not on the actual page.

For a dashboard that can update the website properly, you usually need:

  1. A database or CMS to store posts/articles.

  2. A server action or API route that saves dashboard edits to that database/CMS.

  3. The public page to read the article content from that same source.

  4. Optional revalidation or refresh logic so the page updates after editing.

If this is a blog-style site, I would ask v0 to add persistent storage instead of just a visual dashboard. For example:

“Update this project so dashboard-created articles are saved to a persistent database and the public article pages read from that database. Do not store article content only in local state or localStorage.”

If you want it to work across devices, the key is persistent backend storage. A dashboard UI alone will not solve it unless it is connected to a database/CMS.

Hello Ryu,

Thank you for your assistance. I’ve asked v0 to make the changes, and it did; the issue is that the changes I make wouldn’t sync across devices. I’ve tried to connect the database (Neon) through the Vercel dashboard, but it’s already connected.

Could you give insight into how I should approach this?

Hi Tove, sorry for the late response.

If Neon is already connected in the Vercel dashboard, I would split the issue into two checks:

First, confirm whether the dashboard is actually writing to Neon. After creating or editing an article, open the Neon console/table editor and check whether a new row appears with the title and content.

If no row appears, then the dashboard is probably still using local state, localStorage, mock data, seed data, or an in-memory array instead of writing to the database.

If the row does appear in Neon but another device still does not show it, then the issue is probably on the read/caching side. The public page may still be reading static/cached data, or it may be reading from a different source than the dashboard writes to.

For a Next.js app, I would ask v0 to make sure:

  1. The dashboard writes posts to Neon through a Server Action or API/Route Handler.

  2. The public article pages read posts from Neon on the server.

  3. No article data is stored only in localStorage, React state, or mock arrays.

  4. After creating/updating a post, the app revalidates the affected blog/article pages.

  5. The production deployment is using the same Neon database/branch you are checking in the Neon dashboard.

You can try prompting v0 with something like this:

“Audit the app’s post/dashboard persistence. Neon is connected in Vercel, but dashboard edits do not sync across devices. Remove any localStorage, mock data, seed data, or in-memory arrays used for posts. Make dashboard create/update/delete actions write to Neon using server-side database code. Make public blog/article pages read from Neon. After every write, revalidate the affected blog and article routes. Add logging/error handling so I can confirm inserts and updates are actually succeeding. Also verify the production deployment is using the correct Neon environment variables/database branch.”

One more thing: since you mentioned the content is visible in the console but not on the page, also check the rendering layer. If the data is fetched correctly but not displayed, it could be a field mismatch like content vs body, a component not rendering the article body, or CSS hiding the text.
