How can I change the HTML title tag of the welcome page?
you can find all here /usr/share/jitsi-meet
I changed title.html file. when i load the welcome page my title comes for a second and then again gets replaced with Jitsi Meet Title
change it in interface_config.js
You have to change the interface_config.js, look into the line 31:
APP_NAME: 'Jitsi Meet', NATIVE_APP_NAME: 'Jitsi Meet', PROVIDER_NAME: 'Jitsi',
Also you have to edit libs/app.bundle.min.js and search for That home page Free Conferencing text and replace that too, if you want it.
There is also a lang/main-enGB.json but editing there doesn;t do anything. Also for logo change go to images folder and replace watermark.png logo with your png logo and jitsilogo.png with your own logo.
