https://github.com/JesperCph/revalidate-tag-issues-reproduction

To Reproduce

1. Build and start the app using pnpm build & pnpm start
2. Open the app at http://localhost:3000/
3. Time is fetched from /api/time, displayed on the landing page, and cached for 60 seconds with the tag time.
4. Navigate to the "Revalidate (page)" using the link, which triggers revalidateTag('time').
5. Navigate back to the "Home" page ('/'), should fetch the updated time from /api/time and display the new value.

Issue
This workflow works as expected in [email protected] and below, but in versions above 14.2.10, including next@15, the tag "time" is not revalidated on visiting /revalidate/page.tsx

Callen revalideTag() within a POST server action, works as exspexted. This can be tested by clicking
Revalidate (Form Action) from the home page, which updates the time.

Current vs. Expected behavior

Current:
The time on the home page / is not updated when navigating back and forth between /revalidate and / using the links.

Expected:
The time on the home page / should update with the value from /api/time when navigating back and forth between /revalidate and / using the links, as the revalidateTag('time') function is called from /revalidate/page.tsx.
