I don't have access to sales, invoices, or clients. my boss has not changed anything so we don't know why this is happening.

Hi there, @user89134.

I hope your week was good so far. I do recommend Clearing Cache and Cookies. Doing this will help periodically clear the cache to allow your browser to function more efficiently. Browsers will normally clear cookies that reach a certain age, but clearing them manually may solve problems with web sites or your browser. A browser's history is a log of sites that you visit.

To clear cache and cookies go to Clear Data off your Browser. This will show the missing Sales, Invoices, or clients. If this doesn't recover the missing features, it means the master admin has changed the view on what the users can see and do. I recommend reaching out to whomever it is and aware them of the issue.

Please reach back out if you have any more questions or concerns. I'm always here lending a helping hand.
