Hi there,
Ideally I'd raise this as a UX defect directly to Atlassian.
We've noticed that the search box at the top of any given confluence page is one of the last things on the page to initialise – in most instances it takes multiple seconds before a user can type into the search box and start a search.
We are a large user of Confluence and searching is the best way to get around our many confluence space(s), so it's eminently frustrating to have to wait to search most times I open Confluence to find something.
Anyone else having the same issue?
