After restarting my phone, some of the apps pinned to the home screen randomly disappear each time. It has been happening since upgrading to android 8.0. I thought that android 8.1 might fix the problem, but it didn't. The worst thing is this happens every time I update as well (obviously the phone has to restart). I live in the UK, am currently running the June 1 2018 security patch and my model number is TA-1024. I'd be grateful for any help. Thanks.
