Tired from clicking "Load Earlier Messages" ?
Well , here is the solution , just by a single tap and voilaa!!
Note : Normally when you press "Load Earlier Messages" one old page of chat is loaded , so by adjusting the slider in the settings (Check screenshots) , you can choose the number of pages to load (1-->100)
