My company i splaying around with Portfolio. As we've evolved so have the portfolio links that were shared with us. Under Portfolio>recent Plans I want to remove the ones that are not applicable for me. In the actual plan I can delete it. Will that delete just from my view of everywhere?
Deleting a plan will delete it for everyone. This won't delete the issues in Jira but it sounds like this isn't what you want to do.
The "recent plans" will show your most recently visited plans. There's no way to "delete" these from the list, but they could be replaced by viewing other plans.
Hope this helps.
