It seems like "Object" one the top menu is gone. Trying to access add perspective in 2019 version but no OBJECT tab. Is this a glitch? cannot pull up where I can even add this back onto the headers.
TIA
Easiest way to correct it is probably to right click anywhere in the Menu bar, then Customize > Menu bar > Reset to Default.This should bring back the Object menu (and reset all customizations you have made to the bar).
I have 2019 version. I have done as you have explained but it has not reinstalled the Object button
Maybe you should update your version?
