Some newly installed apps are not showing up in the app drawer so I cannot add them to screens. I have to launch from Google Play. Google Pixel, android 9.

This morning, without any action on my part, a bunch of icons changed to generic android icons. They’re incorrect in the app drawer, too, but look fine in Pixel launcher. Phone, Contacts, YouTube, Google, Calculator, Calendar. Restart didn’t fix. Oreo on Pixel. LL 14.1.5 r2893

Can someone point me to instructions about moving my setings/layout to a new phone?

I was able to do an export (.lla file), and put it in Dropbox, but not sure how to bring it into my new installation.
