Latr is gone from this browser.

If it stopped working, it was probably one of these

• Nothing arrived at the time you set. Latr fires through your browser, so the browser has to be running. If it was closed, the reminder arrives the next time you open it - and says that it is late. How to check.
• No notification appeared at all. Chrome can be allowed to notify while the operating system is still blocking it - macOS Focus and Windows Focus Assist both do this silently. The two settings.
• Too many of them. Quiet hours, per-site rules and a lower default priority all exist for exactly that. Every setting, explained.
