Tinode freezes while changing between chats

[JavierPeraltaLodisna]

Describe the bug
I've just downloaded Tinode via github in my pc and I only modified Postgres connection and removed register confirmation by email.
The bug I have is: when i send a message to a user and I change to another chat, some random times Tinode freezes for 5 seconds. If I don't send a message at the beggining it doesn't freeze.

To Reproduce
Steps to reproduce the behavior:

1. Send a message to a user
2. Start changing to other user's chats until it freezes (I think it only freezes when you change between 4 or more diferent chats).

Environment (please complete the following information):

• OS: [Windows 11]
• Browser [Microsoft Edge]
• TinodeWeb Version [latest, iv'e just installed it]

Console log
No error in logs, just freezes without any error.

[or-else]

Please open Developer Tools in your browser, save the console log to a file and post it here.

I would first verify that you have unrestricted internet access.
