Link all devices to your admin account from Settings > Users > Devices.
I have try this operation, I click on Settings > Users > admin > Devices, but I can't check on any device.
My traccar server version is 4.0 and the docker images is download from hub.docker.com
Are you using Firefox?
Yes, FF 62.0.3
Click slightly to the right of the checkbox.
O, I try the same operation on IE 11, it works, all device can be checked.
Ha ha , FF is so stupid........>:<
another thing I did notice is that if you disable, then the username: admin this account is no longer valid. comes back as an error 500 good thing I made sure my other account is an admin . just a note to remember to make sure you have another account with admin privileges.
I am the traccar server manager, and my server has some register users, so how can the admin has permission to view all device?
