+The first user created automatically becomes an admin and can log into PocketBase.

+Try upgrading your docker version on the agent system. I had this issue on a machine running docker 24. It was fixed by upgrading to version 27.

 ### Month / week records are not populating reliably
 
 Records for longer time periods are made by averaging stats from the shorter time periods. They require the agent to be running uninterrupted for long enough to get a full set of data.
