Traccar 5.8 - Cannot change speed unit per user

Hi to all

as per title i am trying to set a specific user to Km/h in User / Preferences / Speed Unit
this setting has no effect for the specific user

the only way to change the speed unit is to change Server / Preferences / Speed Unit, but this effects all users
i tried loggin out and logging in again for the specific user with no effect
the only thing i did not tried is to restart the server

i am missing something?
thanks in advance for any imput on this

Yes, you must be missing something.

thanks you for your reply, but since i am stuck and i think i made all the tests i coulds do, the reply does not help a lot
can you be a bit more specific please?
should i provide screenshots?

i think that changing the preferences of the user / log off and log on again should do the trick
when i change the server preferences from KN to Km/h, is see the change for all users whithout deleting cookies or browser history. Page refresh is enough

thanks

I don't really know what you're missing. One possible option is that you set to force server settings.

Thank you very much Anton
right to the point

I very much appreciate your support
