— Dates blink when scaling (the attached video #1).
— 'Joined' and 'Left' buttons are missing checks. 
— The app slow and laggy when filtering the graphs (the attached video #2).
iPhone 6s, iOS 12.0.2

Major issue: 40-44 fps during 1st chart scaling on iPhone 6+, 25-30 fps on iPhone 5. For more details read my comments about performance of entry213.
