When generating a link to a puzzle, the UI should display a warning if the generated link is more than a certain number of characters.
When a URL is too long (possibly 8,192 chars according to a quick search), it can trigger a request URI too long error and be unable to open in the browser. The workaround for this is opening the Penpa UI and clicking the "Load" button to load a URL through the app, but it's not obvious to infrequent users and could use some UI to prompt the setter to review the instructions.
