COMEA COME download notification was dismissed
Dismissing a notification can hide the progress display without deleting the file. Check the browser's Downloads view to see the actual state.
Inspect the transfer list
Look for the intended item and read whether it is active, paused, failed or complete. The absence of a notification is not enough to conclude that the transfer stopped. Avoid pressing the page's download button again before checking.
Resume through the owner
If the browser reports a pause or failure, use its own controls and inspect connection or storage messages. If the file completed, continue from that item. Notifications and saved-file actions are separate parts of the interface.
Keep one clear attempt
Do not create several copies just to get another notification. Match the chosen file with its source and time, and leave partial items unopened. If Android later reports an error, record that separately.
A useful next step
Continue from the browser's verified state rather than the notification's visibility.
