My PDF download failed or is taking a long time

The full planner takes a few minutes and one page usually takes under a minute, and you can keep working meanwhile. If something goes wrong, the message on screen says what happened:

• That planner was just exported. You can make a PDF of the full planner once a minute, and of a page every 15 seconds. Wait for the countdown, then try again.
• Your PDF is already being made. One is on its way. Select Download as PDF again after a few minutes to get the finished file.
• Your PDF is taking longer than usual and is still being made. Wait a minute, then select Download as PDF again.
• Something went wrong while making your PDF. Try again in a few minutes.
• That page is no longer in the planner. The page was removed after you chose it. Go back to the page you want and try again.

It said it downloaded, but I can't find the file

Check your browser's downloads. The message that says Your PDF is ready has a Download again button (Open again in the desktop app). And if nothing in your planner has changed, selecting Download as PDF again brings the finished file back almost straight away.
