iOS 13.3.1Upgrade lost contacts and can’t resurrect via iTunes
Upgraded iPhone to iOS 13.3.1. Downloaded some music to PC and synced iPhone via iTunes. All my contacts appear to have been lost. Synced via iTunes again this time telling iTunes to replace all contacts on iPhone - still no contacts. NB contacts are synced with Outlook, not iCloud. Backups to PC, not iCloud.
iPhone 7, iOS 13
