Welcome to the community. I would like to know few more facts before I can help you. I need to know the device os and version, when did you do the update, have you use any clean app recently? Also, do not reinstall the app or you will lose all your boosters.
Samsung tab A (2016) had two Android system upgrade to 8.1,have you done that. If you do the next step would be to clean your system's memory and cache. I use Noxcleaner app, it allow you to scan for virus and remove unnecessary file from memory and storage. If you need a step by step instructions for both operations please let me know. After that try reinstall again.
Try the following: (1) go to the app uninstall page. (2) tap "storage", (3) tap "clear cache", (4) tap "clear data" press ok, Restart the app, if not work then reinstall again.
