Ever since the Android 11 update on my Xperia 1 (J8110) any home screen shortcuts seems to disappear after a few days, usually going after a restart.

ie. If I'm using Chrome find a website that you want quick access to, use the option to "Add to home screen" it'll create a short cut on your home screen that takes you to that particular website.

Now I can use this shortcut to quickly access that website. But..... This shortcut only seems to stay on the home screen for a short amount of time. At a guess it'll disappear after about a week to 10 days and usually after a restart.

It's not just chrome shortcuts either, my satnav has this option to create shortcuts too and they also disappear in the same manner.

Chrome, edge, Firefox, maps, satnav etc etc.

It's like Android 11 has been doing some kind of clean up on a restart.

How can I stop this, it's really annoying.
