Icon Glitch – Coursera: Grow your career Review

So far I have no problems actually using the app. However, sometimes the icon on my iPad Mini will change into this geometric design. On that state the app is un-openable. Currently, to resolve the issue you have to rearrange the apps and then back out of that. Is anyone else experiencing this issue?
