Unresponsive & Laggy On My iPhone 7 Plus

Pages is a great word processing app and Ive always enjoyed using it both for school and personal projects. However, ever since I downloaded it on my iPhone 7 Plus, Ive been experiencing issues such as constant crashing when changing fonts or moving text boxes. Also, when moving elements such as text boxes, charts, or images there is a sluggish delay when I swipe. Very disappointing.
