For case (b) I tested the "mffrequentlanguages" entrypoint (this is the 'campaign' URL parameter for this entrypoint) in production wikis and the event seems to be properly logged with "frequent_languages" event source.

EDIT: As displayed in the screencast, the case (c) also seems to not be caused by some actual issue or bug, as the "frequent_languages" entrypoint is properly displayed for logged-in users and the user information are also properly logged in the "dashboard_open" analytics event.

Additionally, regarding case (a):

• the issue for the "recent translation" entrypoint is already being handled in T316762, so there is no reason for a duplicate task here.
• the issue for the "recent edit" entrypoint is indeed still pending, but the original ticket for this entrypoint is still open (T287025), so again I do not think there is a reason for a duplicate task here.

@Pginer-WMF based on my input above, I would suggest that this task can be closed.

Thanks for the input, Nik. I added a note on T287025 to make sure instrumentation is verified. All other aspects of the ticket seem clear now. Thanks!
