To clear the cache for Messenger on various devices, follow these steps:

For iPhone and iPad:

  1. Open the Settings app.
  2. Navigate to "General" > "Storage" (or "iPhone Storage").
  3. Locate and select the Messenger app from the list.
  4. Choose "Offload App" to free up storage without deleting your account data and documents; or "Delete App" to remove both the app and its data entirely. If you choose to delete, you'll need to reinstall the app later.

Alternatively, you can simply log out of the Messenger app, which will clear the cache upon signing back in.

For Android Devices:

  1. Long-press the Messenger app icon.
  2. Tap the "Info" or "i" symbol that appears.
  3. In the app info page, locate and tap "Storage."
  4. Choose "Clear Cache" to clear temporary files, or "Clear Data" to erase all data including login information (you'll need to log in again).

For desktops, clearing the Messenger cache involves clearing browser data:

For Google Chrome on Desktop:

  1. Open Chrome and navigate to Messenger.
  2. Click the lock icon in the address bar.
  3. Open Site Settings.
  4. Clear Messenger data.

For macOS Users:

There is no built-in feature to clear specific app caches on macOS. Instead, you would typically use a third-party tool like CleanMyMac X to scan and clean system junk, including Messenger cache.
