I tried adding the screen function with an empty test function to no avail. If I change the slug to $bp->profile->slug then the Sub Nav item appears as a sub item of the Profile Parent tab but seems not to work with my custom added “TEST” parent.
It seems like its a slug issue, but whether I am declaring,
‘slug’ => $bp->account->slug
or ‘slug’ => ‘account’
…it still doesn’t seem to take. When I dump the $bp global varaible, I can see my parent menu item exists as it should, so that doesn’t seem to be the issue. Thanks for your input thus far.
