Play Store does not download apps

[Android Central Question]

Have tried clearing cache, force stopped Play Store and Download Manager.
Even downloaded a newer version APK.
No data restrictions.
Downloads freeze at 100% and then nothing happens. Apps no longer update.
I've tried all the suggestions I could find.
Recently updated to Pie, on an Xperia XZ2.
