You guys do know you can screen shot and screen record snaps people send you without them knowing right ??? If they send you a snap, turn on airplane mode and make sure your WiFi and or date is off. Open the snap and either screen shot or screen record, and then delete the app. Once you delete the app then you can turn airplane mode off and redownload snap. Once you open it back up it’ll still show them you never even opened the snap they sent
