Board changes from other users are not synchronized without a manual page reload

[MK-Nadine]

Hi.

Currently, when multiple users are working on the same Deck board, changes made by one user are not automatically shown to the other users. The board does not appear to update in real time or through periodic background synchronization. Other users only see the changes after manually reloading the browser page.

Steps to reproduce:
Open the same Deck board with two different user accounts in separate browser sessions.
With the first user, create, edit, move, or delete a card.
Observe the board opened by the second user.
Wait several minutes without reloading the page.

Result: The changes made by the first user are not displayed for the second user. The board remains unchanged until the second user manually reloads the page.

Expected behavior: Changes made by other users should automatically appear without requiring a manual page reload. Ideally, updates should be synchronized in real time. If real-time synchronization is not supported, the board should at least refresh its data automatically at regular intervals.

Impact: This makes collaborative work on shared boards difficult because users may unknowingly work with outdated information. It can also lead to conflicting edits, duplicate work, or cards being moved based on an outdated board state.

Thank you!

Fairly sure this works for me - do you have notify_push installed and configured?
