[2.1.27] iPhone 7 / 10.2.1 - User is able to Like lomotif after double tapping on "Like" (Heart) icon on "Following/Lomotif Preview" screens.

Frequency: Every time.

Precondition: There should be some lomotifs under "Following/Lomotif" tabs.

Action: 1: Launch the app and login with a valid credential. 2: Navigate to "Following" tab. 3: Double tap on "Like" icon (Observe, Like count will not increase). 4: Check if lomotif is displayed as liked.

Expected result: User should be unable to like lomotif after double tapping( the first tap should be like and the second tap should be unlike and vice versa.)

Actual result:

• The user is able to like lomotif and like count is not increased. (Like count is set when the user navigates back to "Following/Lomotif Preview" screens from "Like" screen.)
• The user is receiving notifications for like.
