I managed to fix my problem with messenger when i couldn't login after i cleared its cache and data. The reason why i did it because i assumed that after clearing its data and cache the speed of app would return but it didnt. I reinstalled messenger but the speed at which the message is sent is slow, its takes more than 1 second for the message to be sent, my other phone uses an older version of messenger and while only using free data when message is sent its instant, fix it
