Can't make pdf of invoice anymore

I upgraded from version 20.2.31 to 23.10.2.1021.
When I made an invoice, there was always a button “pdf” next to “print”.
Now with the new version I can’t make a pdf anymore.
See attached photo

Thanks in advance,

Why not to the current version 24.4.17.1441 download at https://www.manager.io/download ? Especially because the forum rules at FAQ - Manager Forum state:

Manager advances very quickly, simplifying and adding features and capabilities. Sometimes, bugs occur with new releases. But these are usually fixed rapidly, often within minutes. So if you encounter a problem with the desktop or server editions, update Manager , even if you recently did. (The cloud edition is always up to date.) You can check the latest version at https://www.manager.io/desktop/download/

To answer your question. The internal PDF generator was put into Obsolete Feature in Settings. You thus have to go to Settings → Obsolete Features and Enable Internal PDF Generator.
