<(PPM) Support Tip>: Limitation about the number of items added to Personalized Dashboard page
Limitation about the number of items that can be added to the Personalized Dashboard page:
You can add no more than 20 items (pages or groups) in the Private pages folder of the Personalized Dashboard page.
It is recommended that you group some pages if you exceed the limit and still want to add items.
If there are more than 20 menu items there are browser related issues.
There is a documentation defect, to document this in the PPM guides:
