This is one of the most common problem user faces. I was having the same issue, so in order to resolve it, just follow the mentioned steps (it worked for me)

1. Un-install the app
2. Delete the cache and other files of the apps (do it via file manager)
3. Restart your phone
4. Re install the app

and the issue will be fixed. Do let me know if you are having problem performing the steps which I have mentioned above or if the problem is still there. Would love to help!
