I started to notice 'unspecified' appear across many dimensions starting last week. Does anyone know why?
This is causing problems with many segments and dashboards I've already created, as it will be a lot of work to go into all my reports and dashboards to filter out 'unspecified'. It also causes an additional filter step when creating future reports.
Hoping to understand why this started to happen all of a sudden, and if it can be excluded from the back-end?
