Hello,
modern sites on my site collection do not have a working edit button. The issue is inconsistent, Previously it was working but from last couple of days Edit button is not showing.
I have full control over the entire collection, so permissions shouldn't be the issue.
I tried multiple browsers, windows clearing the browser cache, and have determined that it's universally affecting all users regardless of browser.
Tried to add "?ToolPaneView=2&Mode=Edit" to the url to check whether they could be edited still it's not working.
I can confirm that these sites were editable a couple of days ago, After, Did R&D on that i came across to know that i need to install latest Sharepoint updates.
So i updated kb5002135 to kb5002180 though it is not visible.Run the SharePoint configuration wizard but still same issue.
