macOS Mojave: Command + Shift + 4, screenshot not getting saved anymore When I press Command + Shift + 4 and take a screenshot, the screenshot shows as a thumbnail at bottom right of the screen.

If I continue working, the screenshot is not saved. I have to double-click on the thumbnail, open it in Preview &amp; save it.

How do I save the screenshot immediately like it used to?

The answer here doesn't really apply as I don't see a Touch Bar.
Use the keyboard shortcut Command + Shift + 5 to invoke the screen capture app. Click on Options and check if the Save to location is set correctly.
