Rocket.Chat Desktop App Version

Rocket.Chat Server Version

Describe the bug

Often, chats refuse to load.

Even reinstalling the app, the chat only loads for example to 1 week ago (say december 1). But there are many new messages up until December 7.

Messages all load on the Mobile version, so I know they are there.

Web version has the same issue.

How to Reproduce

Set up server channels with E2EE, 12 members
Post many messages

??

Sometimes it works fine. But very often also, messages don't show.

Describe your Expected behavior

All messages load, like on the mobile app.

Anything else

We switched to RocketChat last month.

We had many glitches like this but usually it was recoverable.

This one seems persistent though.

The issue names no files, tests, or entry points, and its reproduction steps are incomplete. Start by reproducing the missing-message behavior on macOS 26, Rocket.Chat 4.10.0, and server 7.12 with an E2EE channel, then trace message loading and compare it with the mobile result; done means all messages load consistently in the web and desktop clients.
