The Likes tab displays all your previous liked photos and videos. Visually, it behaves identically to that of the Feed view. To view items you have saved, see Profile.
Your Likes tab is limited to the 300 most recent likes you have made.
As of version 188.8.131.52, the Likes tab is no longer enabled by default in the Flume main menu and can be instead accessed via the Profile settings menu. You can enable it in the main menu via the Menu Preferences.
