Im trying to get some amplitude identifier in JS (browser) to identifiy/match the current user in other systems…
i've tried to use deviceId, but
```
amplitude.getInstance().getDeviceId()
```
returns 'shared-anonymous-device'
i've tried also getSessionId… that returns session that does not exists in amplitude
ive checked
amplitude._instances
to see if there are not more instances for some reason but no, just $default_instance
we are using amplitude wordpress plugin
ive tried differnet browsers, ip addresses (vpn, no vpn)… its still the same
