User configuration not persistent

If I save configuration, e.g. favourtie channels then open a browser on another device or sometimes on the same device, this config is reset, e.g. there are no entries in the favourite channels list.

User settings are stored as 'cookies' in the browser, in the same way as the Tvheadend UI. The cookie lifetime is 10 years.

Understood! Thanks for explaining this. It isn't a great way to store user configuration and I am suprised that tvheadend does this! (Indeed, when I change a user setting in tvheadend's webgui, it changes for other devices too - so does not seem to be pesisted purely in cookies. Maybe there is a push-to-server API call.) User config should ideally be persistent for the user from any device and not depend on them setting up their preferences on every device they use. I guess many users will only access this from the same device so it may be of limited impact but I would recommend user config be stored elsewhere.

Tvheadend's cookies store things like the column choices for the grid displays and the user's status level. There isn't a way to store data on the server.

The PHP version of TVHadmin on the other hand stores config settings on the PHP server - including the Tvheadend user credentials - which means that everyone gets the same settings.
