Phone to Phone Transfer appears to not transfer all files?
For phone-to-phone transfers version iPhone IOS 15.1 does appear to move all settings, apps, and associated data files. Have performed complete iCloud AND iTunes encrypted back up BEFORE using the direct phone-to-phone transfer (or quick start) method in transferring data from iPhone 8+ to iPhone 13 Pro Max (both on IOS 15.1 before the transfer). "Most" of the apps, data, settings, transferred BUT several key apps and data did not. What procedures / options are available to make / recover these key apps available on the "new" iPhone?
Windows, Windows 10
