The one below is still operative, but was getting long
I'd be surprised if any of this matters directly, but it may provide clues for debugging:
Retried the approved proceedure (select orange box / apply & update graph / switch view|section) varying whther I was in light or dark mode and whether the page I was leaving used either a compact or non-compact header.
In all cases the date range selection reverts to the default Last 28 days when switching.
When moving from the dashboard [ member/>name</analytics/ ] to any of the explore analytics pages (e.g. analytics/content-impressions/) the page header automatically sets to compact [This reoccurs if I manually reset the page header to non-compact and refresh the page.]
(when activating the dashboard page member/>name</analytics/ everything is fine)
The compact header (regardless of on what page I use it) show my level as 38 and my percentage progress as 28% (both correct), however,
the total XP earned is missing completely (including the colon)
I have no level title shown
after the 28% it say ":
1 / 2 xp"(the thermometer seems to be correct)
When switching for light mode to dark (or the reverse) the graph[s] shown on any of the pages (including the dashboard do not update).
[I wouldn't think this 'bug' is worth fixing, but the behavior is included for any clue it may give.]
