Deleted apps still shows up in home screen and cannot delete the blank app
I deleted an app last 2 weeks. However it appeared again after I deleted it within 5 mins. Then I restarted my phone and the app still exist but showed in a white blank app appearance.I deleted it everyday but it re-appeared an hour later. And I couldnt delete it or offload it in Setting. I dont want to go to any apple store to fix my phone. How can I solve this problem myself? I dont own Mac PC. I own a windows computer. I followed the instruction that you replied in a similar post but failed. PLease reply me ASAP. Thank you.
